Power management webminar



Vehicles usually take 2 types of battery voltage: 12V or 24V. However, Acrosser’s power manage subsystem has a wide range for power inputs that cater to both batteries. This could also protect the system from unstable power surges during the vehicle’s operation.

Large energy consumption may occur while operating the car computer. To prevent the power loss, Acrosser’s In-Vehicle computer offers low voltage protection to monitor the main battery. Once the voltage goes below its pre-set value, the computer will shut down and save the energy for vehicle use.

When the In-vehicle computer power on/off mode is controlled by the car ignition, it is impossible to turn off the ignition and turn it back on just to restart the computer. If the vehicle’s ignition switch did not power up the computer properly, Acrosser’s power management subsystem will automatically detect and monitor the system status to restart the system upon retry.


ACROSSER Technology has provided a complete product line for In-Vehicle computers. The product line also gained more attention after winning the 21th Taiwan Excellence Award with 2 outstanding In-Vehicle computers: AR-V6005FL and AR-V6100FL. Acrosser also released its latest in-vehicle computer, AIV-HM76V0FL during late 2012. The company pride itself in offering not just products, but solutions.

Creating the Raspberry Pi credit card sized

Embedded PC, in vehicle PC, Industrial PC

The initial goal in creating the Raspberry Pi credit card sized, Linux-based Single Board Computer (SBC) – targeted primarily at education – was to develop a response to the decline of students engaging with computer science and related engineering disciplines. Our desire was to reverse the trend of children becoming consumers rather than creators. The following case study follows the hardware development process from an early failure, initial prototypes, and through to the finished production design.

Over recent years there has been an increasing trend for children to be consumers of digital content rather than be future creators or engineers. This trend is driven by manufacturers looking to provide a seamless experience for target customers on a variety of electronic platforms, from gaming consoles to tablets and laptop computers.
As a result, access to raw I/O has become restricted. Similarly, any packaged provision of a programming environment is an anathema to the products’ commercial goals.

Advances in EDA design methodologies led


FPGAs have become some of the most important drivers for development of leading edge semiconductor technology. The complexity of programmable devices, and their integration of diverse high-performance functions, provides excellent vehicles for testing new processes. It’s no accident that Intel has selected Achronix and Tabula, both makers of programmable devices, as the only partners that have been granted access to their 22 nm 3D Tri-Gate (FinFET) process. In February, Intel also announced an agreement with Altera, which will enable the company to manufacture FPGAs using their next-generation 14 nm Tri-Gate process.
Embedded PC, in vehicle pc, Single Board Computer

In parallel with driving manufacturing, FPGA technology development must also include enhancements to design tools and flows. As vendors strive to make their devices more SoC- and ASIC-like, they are also adopting standards and collaborating with EDA companies to integrate their tools more seamlessly. These collaborations are producing great benefits for designers, as FPGA design methodologies are leading the way in areas that the EDA industry has long been promising new capabilities, such as in Electronic System Level (ESL) synthesis, IP integration and re-use, and higher-level tools for software/hardware co-design.
FPGA design methodologies have long integrated EDA point tools, such as simulation and PCB design, into FPGA vendor’s design platforms. Now, vendors such as Synopsys, with their Synplicity tools, and Xilinx with Vivado, are collaborating to build more complete integrated top-to-bottom flows. To address the greater complexity of FPGAs that may now contain up to two million equivalent logic cells, Synopsys has added Hierarchical Project Management (HPM) to Synplicity. HPM supports distributed design teams and parallel development, enabling partitioning of RTL and sharing of design debug tasks. Xilinx has adopted the industry-standard  (SDC) timing constraints (to replace Xilinx proprietary UDC) in a design flow that can be driven from standard Verilog HDL.

Latest configurable Analog Front End (AFE) simplifies interfacing to hundreds of sensors


Embedded PC, in vehicle pc, Single Board ComputerMany of today's embedded systems incorporate multiple analog sensors that make devices more intelligent, and provide users with an array of information resulting in improved efficiency or added convenience. The Analog Front End (AFE), allowing the connection of the sensor to the digital world of the MCU, is often an assumed "burden" in designing sensor interface circuits. However, the latest concept in a configurable AFE, integrated into a single package, is helping systems designers overcome sensor integration challenges associated with tuning and sensor drift, thereby reducing time to market. The following discussion examines how the versatility of such a technology allows the designer to tune and debug AFE characteristics on the fly, automate trimming and adjust for sensor drift, and add scalability to support multiple sensor types with a single platform.

The ubiquitous use of sensors in our smart devices – from cell phones to industrial equipment and even medical devices – has increased the need for more intelligent sensor technologies that are more versatile, lower overall costs, and require fewer resources to develop and maintain.
Most analog sensor systems comprise three key elements: the analog sensor that measures a specific form of energy, the micro controller (MCU) that processes the digital equivalent of the sensor’s signal, and between them is the Analog Front End (AFE) system (Figure 1). The AFE receives the sensor’s signal and converts/transforms it for the MCU to use, as in most cases the sensor output signals cannot be directly interfaced to an MCU.
Embedded PC, in vehicle pc, Single Board Computer
Figure 1: The Analog Front End (AFE) converts and conditions analog sensor signals for use by the MCU.

The challenge associated with current AFE design approaches is the time-consuming trial-and-error tuning process, and the lack of flexibility and scalability to support multiple sensors from a single AFE. Moreover, many AFEs do not account for sensor drift or adjust for sensor trimming during production, which directly reduces the quality of the sensor. However, new fully configurable AFE technology is enabling designers to overcome these hurdles.
The importance of the AFE
The AFE itself performs multiple functions, depending on the application. One function of the AFE is to amplify signals that are too weak for the MCU to read. The AFE circuitry employs amplifiers to provide output voltages that are hundreds or up to thousands of times larger than the voltage provided by the sensor. This is typically done with op-amps that can vary widely in cost and power based on the required characteristics. Depending on the sensor characteristics, the AFE amplifier structure will vary. For example, if the sensor output is differential and low impedance, a simple differential input can be used. If, on the other hand, the sensor output is differential and high impedance, a more complicated instrumentation amplifier, with matching high-impedance inputs, may be needed.
Another function of the AFE is to filter unwanted frequency ranges from the sensor, for example, to satisfy the Nyquist limit or to remove a DC offset. This noise must be removed before the analog signal is converted to digital. The AFE must employ low-pass filter circuitry to block out high-frequency noise and/or employ high-pass circuits to remove lower-frequency noise.
A third function of the AFE is to convert signals from one signal type to another. For example, typical sensors output a voltage, but some output a current. The MCU ADC circuits do not accept current inputs, so such currents have to be converted to voltages before going to the MCU. This current-to-voltage conversion is performed by the AFE circuit, called a transimpedance (I/V) circuit, which also amplifies the resulting voltage to levels usable by the MCU.
Challenges to AFE designs
Most AFE circuits are custom designed to meet the electrical requirements of a particular system under development. Engineers must design the circuitry, select the appropriate ICs and passive components, then test and tune the resulting circuit and PCB layout. In many cases, this takes a trial-and-error method to calibrate the right analog circuit design. This iterative tuning process is time and resource consuming, adversely affecting development cost and time-to-market. In addition, the AFE is often difficult to simulate and must be adjusted because of specific component behavior, board layout, and nearby noise sources.
There is also limited or no scalability of the AFE circuitry to support multiple sensors, let alone multiple types of sensors (that is, different topologies). The AFE circuit is designed for one particular sensor, making it difficult to swap one sensor for another using the same AFE – even if they employ the same topology.
Finally, sensors need constant tuning either during production – adjusted for sensor trimming – or because they degrade over time and cannot easily be corrected after they are deployed in the field. Fixed-component AFE designs do not correct for sensor drift nor are they easily adjusted for sensor trimming. A software-supported design approach can help.
Let’s examine each of these challenges.
Configurable AFE eases calibration trial and error
Looking at the hundreds of different types of sensors available, one can observe common topologies and signal characteristic ranges and understand that having the ability to simply change the characteristics of the op-amps, or to dynamically change the gain values, will significantly reduce the complexity and reduce development time.
The Renesas Smart Analog technology is an example of a fully configurable AFE technology that allows for such capability. As Figure 2 shows, such technology includes five elements: three separate configurable amplifiers, an additional amplifier with sync detection capability, a general-purpose op-amp, a low-pass filter with variable cutoff frequency, and lastly, a high-pass filter with variable cutoff frequency.
Embedded PC, in vehicle pc, Single Board Computer
Figure 2: Diagram of a fully configurable AFE with an optional integrated MCU

The design engineer can create the desired custom AFE circuitry by simply setting the main parameters for these various circuit blocks, and then selecting the connections between these blocks. Three highly configurable amplifiers can be used to produce a tailored I/V transimpedance converter/amplifier, a noninverting amplifier, an inverting amplifier, a differential amplifier, or a summing amplifier. The chip can be custom configured to implement a range of signal amplification gains, and it provides an adjustable span of signal voltage offsets.
Additionally, the amplifiers in this IC can be configured to implement a single-channel, high-impedance instrumentation amplifier. This type of differential amplifier is essential for interfacing to high-impedance sensors such as piezoelectric types.
As the AFE takes care of amplifying/filtering/converting the signals from the sensor, the MCU (internal or external device) can analyze the AFE signals to dynamically change the gain values (that is, while the system is operating) to compensate for changes in ambient environment. This “closed loop,” self-adjusting AFE structure provides a more robust, intelligent sensor interface.
An integrated AFE+MCU device offers the additional benefit of automating the trimming process as it will read the signals from the AFE and compare that to the known parameters to make the necessary adjustments on the AFE, thereby cutting system production costs. In the same way, the MCU can automatically adjust the AFE gain to counteract the signal-generation deviations expected to occur over time as the sensor degrades.
Configurable AFE provides scalability
While configurability is important to reduce complexity and debugging time, another key design factor is scalability. An AFE with enough connection terminals to accommodate all the sensors typically needed eliminates the traditional requirement to have a separate AFE circuit for each sensor. Handling the entire array of sensors via one AFE helps shrink the circuit board and simultaneously decreases system component counts while reducing power consumption by as much as 20 percent. In fact, because of the simple interface of these AFEs – to just an SPI line and the ADC channels from the MCU – it is possible to connect to as many as 96 sensors using one MCU.
A software-supported design approach
Extreme configurability can come with the burden of tool complexity, so it is important to have a simple software-based design tool that can configure and customize the characteristics of the AFE for that specific application. Designers no longer need to understand the lowest level of the hardware, nor be analog experts when the AFE register values can be simply set, and the topology, gain/offset values, and characteristics can all be done in software.
Such a tool should run on a PC and provide an easy way for selecting typical sensor types, such as pressure, humidity, acceleration, impact, magnetic, and piezoelectric types – supporting multiple topologies and characteristics. The Smart Analog software provides this highly intuitive environment where designers easily set parameters, change topologies, do offset tuning, and have the ability to add filters and, of course, have access to the signal pins.
Because the tool itself already has libraries of different sensor profiles, it is easy for a systems engineer to have a starting point in their design. A graphical representation of the output signals from the AFE can be used to monitor systems with close-to-real-time feedback, which will make it very easy to make the AFE adjustments and tuning. All these features reduce complexity in development and thus reduce resource costs.
Once the configuration is set, the tool outputs a register file that can be used by the software on the MCU. The MCU stores the sensor settings in on-chip flash (nonvolatile) memory within its firmware, and when power is applied to the system, the MCU sends the stored settings to registers in the Smart Analog IC, reconfiguring that chip accordingly.
Simplifying the burden of AFE designs
The AFE is a critical, yet sometimes underappreciated component to a sensor system. The typical discrete approach of adding op-amps and filters, and trial-and-error soldering of resistors is not efficient and the cost of time in debugging and development easily outweighs the cost of adding an intelligent, MCU-based configurable AFE. But not all configurable AFEs are built the same. So, it is important to consider the flexibility and scalability of the AFE to support different types of sensors, and the intelligence to adjust “on the fly” or in the field. Simple, easy-to-use software tools can ease this process and can be used by even the non-analog experts on the team.

2012 Top Embedded Innovator

Single board computer, Panel PC, networking appliance

Kwok Wu has many years of experience in advanced embedded systems and software...

ECD: What emerging trends and challenges do you see in embedded design?
WU: Internet traffic will grow 5x its size in the next three years (according to Morgan Stanley), driven by wireless and video traffic as well as by the Internet of Things, which is connecting an increasing number of sensors and smart appliances with on-demand access via multiple smart handsets. Local wireless routers and access points thus need to become smart gateways, enabled by open-source scalable network platforms, in order to efficiently handle local traffic in homes, offices, and factories.
The #1 theme is a focus on smart residential gateways with the Internet of Things – usually forhome automation and remote monitoring to control sensors including smoke alarms, smart meters, smart appliances for smart energy, and IP cameras for security. For example, Freescale’s MPC8308nSG smart converged gateway with integrated wireless connectivity including 3G broadband, 802.11n Wi-Fi, and ZigBee wireless sensor network addresses many market opportunities in the smart energy/smart grid, health monitoring, industrial and residential automation, and mobile transportation segments.
The #2 theme is a focus on smart business gateways that deliver various cloud services for multi-user collaboration and office-in-a-box, such as unified communications, PBX VoIP, wireless video-on-demand, network video recording, and video surveillance. Office automation is another growth area offering businesses cloud-based services across a large number of users, sometimes in different offices.
ECD: Which engineering specialties are most valuable to your company, and are they difficult to find?
WU: Freescale Semiconductor is a leader in network and communication processors (Power Architecture), ZigBee RF sensor devices, i.MX multimedia application processors, and MCUs forautomobile, transportation, and industrial applications. Freescale’s Power Architecture networking processors offer efficient and scalable performance with secure trusted architecture.PowerPC processors are also used in the automobile engine management and industrial automation markets.
ECD: What is your assessment of the demand for ubiquitous connectivity, and how does it affect your product development plans?
WU: Converged network standards allow more devices to be connected seamlessly. Our product development must be on an open, scalable platform that can adapt to evolving connectivity standards. Our smart converged gateways need to handle multiple wireless technologies (3G, Wi-Fi, ZigBee wireless sensor) all in one gateway.
ECD: How will embedded computing advance in the next 5-10 years?
WU: The “network is the computer” concept promises to deliver cloud-based services through the “network as a service” model. Open-source smart software will provide embedded distributed intelligence that enables smartphones/tablets, smart appliances, smart TVs, smart utility meters, and IP-based programmable communicating thermostats. These smart devices will offer on-demand Internet access through smart AP gateways and smart managed switches and routers, driven by open-source software-defined networks and platforms such as the Freescale smart gateways that won two international networking and communication awards. The key approach is to use an open-source, scalable, portable software platform for networking and communication, such as a software-defined network consisting of OpenFlow, OpenStack, and Open vSwitch.
Furthermore, smart gateways within a campus will be connected by a mesh network to form smart, resilient networks for local clouds. Smart software added to smart sensors and gateways with real-time location and context-aware decision-making will be more pervasive. These gateways will ultimately create safer, greener, more secure, and smarter connected communities (homes, cars, offices, factories) and a rich, personalized connected experience.

Expanding the possibilities of multitouch functionality


With the touch-screen sector now entering a new phase of innovation, the issue of applying multitouch operation to the larger format displays found in industrial and public use settings is becoming a key engineering concern. Designers must examine the sensor technology options available today and consider using new single-layer project capacitive sensing technology to enable sophisticated human-machine interactions in large displays destined for harsh environments.

Multitouch sensor technology has the potential to revolutionize the way we connect with all manner of electronics hardware, giving touch-screen-based Graphical User Interfaces (GUIs) the ability to recognize complex gestures using several fingers such as rotating, two-digit scrolling, three-digit dragging, and pinch zoom, as well as allowing multiple users to collaborate. Analyst firm Markets & Markets predicts that the global multitouch business will reach $5.5 billion by 2016 (constituting more than 30 percent of the total touch panel market by this stage). The multitouch segment is currently exhibiting a compound annual growth rate of more than 18 percent, with the portable consumer sector driving the vast majority of this growth.
Moving forward, the problem for design engineers is knowing how to bring the multitouch capabilities that are already becoming commonplace in smartphones and tablet PCs to other areas that could also derive benefit from them. , Point-Of-Sale (POS), public information, and industrial control systems could profit greatly from this sort of functionality. However, certain obstacles are inhibiting the adoption of multitouch in these nonconsumer sectors.
The larger format multitouch sensor options currently on the market, though acceptable for personal use such as all-in-one touch PCs, have serious shortcomings when applied to more demanding application scenarios. Both infrared and camera-based systems require an exposed bezel for housing sensor elements. This means that, in addition to increasing vulnerability to damage from external forces, the buildup of dust or dirt in the bezel recesses can hamper operational performance over time. These systems also suffer from sensor drift and need regular recalibration to rectify this.
Certain forms of projective capacitance such as self-capacitive types, which by their nature are extremely sensitive in the Z-axis, have proved to be well suited for rugged touch-screen implementations and can measure two independent touch points simultaneously. Another form of projected capacitive sensing, mutual capacitive, which measures charge/discharge across a crossover or node between adjacent cells created by an X-Y grid, tends to be less sensitive in the Z-axis and thus typically only works well with thin glass. However, mutual capacitive sensing offers the ability to detect more than two independent touch points when mated with the appropriate control electronics and software. As a result, this technology has been chosen in recent years as the principal method of bringing multitouch functionality to consumer applications.
Pros and cons of mutual capacitive sensing
The current breed of mutual capacitive touch screens usually relies on Indium Tin Oxide (ITO) as the conductive sensing medium. ITO is already widely used throughout the display industry and provides the benefit of being near-transparent.
Though ITO has been a successful choice in touch screens, it has certain limitations when applied outside the consumer arena. First of all, although conductive, ITO has a relatively high electrical resistance. This means it generally has fairly weak through-glass performance, only able to detect touch through a front overlay thicknesses of ~2 mm. Secondly, ITO is only suitable for use with smaller display formats, as the impedance builds up over the length of the conductive track. This means that sensor systems’ signal integrity levels will not be acceptable once the displays involved have diagonals that are much beyond 22", unless high input power, complex tiling arrangements, or other elaborate approaches are utilized. Finally, conventional ITO-based sensors do not permit flexibility in their production, as each new sensor design or size requires a separate set of photolithographic tools to be created (see Figure 1). This calls for considerable upfront investment and can only be justified if a large enough number of units will be manufactured to cover the initial outlay, which can be anywhere from $5,000 to $30,000 depending on size and complexity.

Consider the example of an interactive digital signage or low-volume, customized POS system. The display formats required for this system would probably be too large for an ITO implementation, plus the limited front glass thickness (typically 1-2 mm at most) is unlikely to be strong enough for the demanding, public-facing, high-use environments in which it would be deployed. Furthermore, in many cases, the specialized nature of an interactive digital signage or POS system means that the number of units produced might not justify the high initial outlay for tooling associated with conventional ITO constructions. As a result, hardware designers wishing to create attention-grabbing, unique-looking user interfaces could be forced to settle for generic touch-screen designs.
Engineers also face technical and economic challenges when trying to incorporate projective capacitive-based multitouch functionality into designs where either large form factors or a relatively small number of units is involved, both of which are possible scenarios in nonconsumer design projects. However, projective capacitance sensing still proves to be the best way to ensure the longevity of touch screens in demanding environments.
A new approach to projective capacitive sensing
The engineering team at Zytronic has developed a mutual capacitive sensing approach that overcomes several significant hurdles, delivering a durable projective capacitive sensing mechanism that can simultaneously support at least 10 independent touch points and be realized on display sizes above 70". This multitouch system is based on the company’s patented Projected Capacitive Technology (PCT), where an intricate sensor matrix comprising copper capacitors 10 mm in diameter is embedded into a laminated substrate.
This substrate can be placed behind a thick protective overlay of glass or polycarbonate to protect it from various forms of potential damage. It can detect touch events through up to 6 mm of toughened glass, effectively doubling the projective overlay thickness that can be specified and thereby providing increased protection from impact, scratches, vibration, and exposure to harsh chemicals or extreme temperatures. Furthermore, this mechanism can be operated by gloved hands, making it highly suited to uncompromising industrial environments, or via a conductive stylus, allowing users to write directly onto the screen.
By utilizing the same proven, maskless plotting process used to produce self-capacitive PCT screens for more than a decade, sensor formats can be scaled up as required, without accruing nonrecurring engineering costs for photolithograph masks. This means that the volume of units does not negatively affect the commercial viability of the project employing multitouch operation, allowing small-volume business to take advantage of this functionality in the same way as it is being sported in high-volume, consumer-oriented products.
The multitouch PCT sensor works in combination with Zytronic’s ZXY200 touch controller. This device processes all touch event data being captured by the proprietary design copper array laminated to the rear of the glass sensor. Using a mutual capacitive approach means that each of the intersecting nodes created in the pattern is individually monitored by the controller running proprietary firmware, which is optimized for the use of copper and lower resistance (hundreds of Ohms/m compared to ITO’s thousands of Ohms/m), plus the resulting improvement in Z-axis sensitivity and ultra-large-size capability. Furthermore, because the copper wires are coated in a dielectric, it is possible to deposit the electrodes in a single process/layer, resulting in a simplified cross-sectional structure to the sensor (see Figure 2). This is not possible with ITO, as multiple layers need to be deposited to create the more complex diamond electrode pattern that this requires, with the X and Y electrodes being isolated from one another.

Energy transfer is localized to the intersection where the X and Y electrodes of the multitouch PCT touch sensor cross. An image map of the energy received is then generated from the measurements, and the position of each touch point can be determined (see Figure 3). With multiple touch points being detected on the screen, true “palm rejection” functionality can be incorporated, with touch performance in no way hampered by users resting their hands, arms, or elbows on the screen. The ability to operate with gloved hands makes it particularly appropriate for use in outdoor environments such as retail and public information applications, as well as in medical and industrial deployments where users need to wear protective clothing.

Innovative, versatile human-interface technology
Projective capacitive multitouch technology has already seen widespread uptake in the portable consumer space, where high-volume and small form factor designs are endemic. The emergence of innovative single-layer technology is now presenting the industry with an economically viable way of implementing multitouch functionality that can be supported both on large format displays and in harsh environments. This sophisticated human-machine interaction could effectively become ubiquitous and as a result, no longer restrict complex gesture recognition or simultaneous manipulation by several different users to portable gadgets.
