The Swiss Center for Electronics and Microtechnology (CSEM) has developed a miniature vision sensor system that enables broad-based monitoring and interpretation of visual data in real time, in any light conditions. The low-cost system, called ViSe, allows original equipment manufacturers (OEMs) to develop application-specific image analysis and response systems aimed at automotive, security, building and home automation, and industrial markets.

The ViSe camera is composed of a vision sensor and a digital signal-processing (DSP) chip that can run identification algorithms. The system speeds throughput of visual data by enabling the vision sensor chip itself to extract key image features needed for interpretation, prior to sending it for software processing on the DSP.

The conventional approach to processing image information involves acquiring an image with a CCD or CMOS camera, converting the intensity distribution to a digital representation, and processing it by means of a digital-processing device. This approach poses considerable problems in certain applications such as automotive or surveillance markets where vision tasks must be executed in real-time and at a low system cost, in environments with uncontrolled levels of lighting.

Unlike other platforms, the ViSe sensor chip captures a detailed image but extracts from the image contrast strength and orientations, permitting it to pass on to the DSP only the key features of the scene needed for analysis. This allows a drastic reduction in the amount of data transmitted off the sensor chip, enabling rapid and low-cost post-processing of imagery in real time.

A ViSe evaluation kit is available and the technology is available for licensing and transfer. CSEM will develop customized software and algorithms for specific applications upon request.

C&D Technologies' ADCDS-1603 imaging signal processor combines true 16-bit resolution with 3 Mpps performance. The unit provides an easy-to-inter-face, functionally complete, low-cost solution for electronic imaging applications that use charge-coupled devices (CCDs) as their photo-detectors.

The unit has a signal-to-noise ratio of 85 dB at 3 MHz with no latency delay. The small, fully integrated 40-pin TDIP package incorporates a user-configurable input amplifier, a correlated double sampler (CDS), and a 16-bit sampling ADC. Further features of the design include edge triggering, gain adjust, offset adjust, a precision +2.0 V reference and a programmable analog input bandwidth function. Overall power consumption is just 500 mW typical.

Central to the ADCDS-1603's high performance is a unique high-speed, high-accuracy, CDS circuit that eliminates the effects of residual charge, charge injection and kT/C noise on the output capacitor of the CCD. This produces a ‘valid video' output signal that the ADCDS-1603 digitizes using its integral high-speed, low-noise sampling ADC.

Two variants of C&D's new imaging signal processor are available: The ADCDS-1603 is designed for commercial applications and has an operating temperature range of 0 °C to +70 °C, while the ADCDS-1603EX has an operating temperature range of -55 °C to +125 °C making it suitable for military and more demanding commercial applications.

Unit pricing for the C&D Technologies ADCDS-1603 is $244 for 100-pieces.

Freescale Semiconductor's dual-core, 32-bit microcontroller (MCU) family is designed to enhance the performance, power efficiency and flexibility of automotive body electronics. The MPC5510 family is the first line of 32-bit automotive MCUs featuring a dual-core architecture with flexible low-power modes. Built on power architecture technology, the MPC5510 family delivers a range of price/performance options and supports extensive communications capabilities, including the FlexRay, controller area network (CAN) and local interconnect network (LIN) protocols.

The MPC5510 family scales from single-core MCUs (with 384 KB of embedded flash, low pin count and reduced feature sets) up to 80 MHz dual-core devices (with 1 MB of flash and advanced communications peripherals). This scalability enables developers to address a broad range of body electronics applications with a flexible platform architecture that extends to other members of the MPC55xx portfolio. Target applications include body control modules (BCMs), gateways (linking FlexRay to CAN and LIN networks), instrument cluster controllers, center stack display controllers and smart junction boxes.

As automotive architectures evolve toward more complex hierarchical networks, automakers require higher-performance body electronics modules to support gateway functions, as well as higher functional integration and centralized services, such as diagnostic, reprogramming and power management. The MPC5510 family addresses these needs with a dual-core architecture based on two e200 cores.

Supported by a crossbar switch architecture and 16-channel enhanced direct memory access (eDMA), Freescale's innovative dual-core design makes the MPC5510 family one of the most efficient, low-power 32-bit automotive MCUs in the market. The MPC5510 family also enables customers to migrate to higher levels of integration in central body electronics and connect the body electronics domain to a FlexRay network. Automakers increasingly are adopting the FlexRay protocol as the vehicle “backbone” network and integrating more functionality into the central body controller.

The MPC5510 family leverages the comprehensive suite of hardware and software development tools available for the MPC55xx family and power architecture technology. Access to this mature ecosystem reduces application development complexity and debugging/validation time during prototyping and software integration phases.

Other feature of this product family include up to 1 MB of embedded flash memory with error correction coding (ECC) and read-while-write (RWW) capability for on-chip data storage, Up to 6 FlexCAN modules, and a single 5 V supply and 5 V analog-to-digital converter (ADC).

Available in 144-pin 20 mm × 20 mm LQFP or 208-pin 17 mm × 17 mm MAPBGA, Freescale plans to offer samples of the MPC5510 family in Q1 2007. A starter kit including an evaluation board and debug interface is planned for April 2007.
