Sawesey, UK Cyan Technology 's new, low cost microcontroller evaluation board comes complete with the company's patented CyanIDE Integrated Development Environment. Selling for only 60 Euros, the combination enables rapid development, configuration and debugging of the Cambridge-based company's 16-bit eCOG1k Microcontroller. The 3.5" (90mm) square board is powered by the USB bus, meaning there is no need for an external power supply. The board features USB-based debugging and a second USB channel is available for serial or parallel I/O user applications up to 1MByte/sec. The board also contains two RS 232 serial interfaces, eight switches and coloured LEDs along with four potentiometers for use with the analogue inputs. All processor pins are brought out to 0.1" headers. Cyan's eCOG1k and µCOG1m low power microcontrollers are based on a Harvard RISC core developed by Cambridge Consultants. Both feature a large number of on-chip peripherals and the 8mm square, 81 pin µCOG1m claims the highest peripheral density of any comparable product. Both microcontrollers deliver high performance at a fraction of the power used by standard devices. Using a single-instruction pre-fetch queue, the microcontrollers boast performance of up to 25 MHz to easily accommodate the 16-bit routines required by many communications applications.

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
