Pyxalis, based in Grenoble, has used Cortus processor subsystems for a high level of software integration dedicated to sensor operation management. The processors offer the possibility to integrate more application-specific image processing functions such as auto-white balance and auto-exposure control.
"By using Cortus processor cores we have been able to offer our customers very flexible sensor operation enabling a lot of different modes depending on the applications," says Philippe Rommeveaux, CEO of Pyxalis. "Cortus processor cores, with their small silicon footprint, complement our Pyxalis IP allowing us to efficiently deliver designs for different market segments," he said.
The team of 20 includes ten designers from e2v Grenoble and combines image sensors with a proprietary high speed analog to digital converter architecture and the APS cores. The die can vary from a few square millimeters up to a single die on a wafer.
The approach of adding intelligence close to the sensor is an emerging trend in the industry, says Michael Chapman, CEO and President of Cortus which is also in Grenoble. "Using a processor core not only offers programmability to end users, but helps the Pyxalis design team efficiency by making derivative designs easier to implement," he said.
The Cortus family of APS processors starts with the world’s smallest 32-bit core, the APS1, and goes up to the floating point FPS6. All cores interface to Cortus’ peripherals including Ethernet 10/100 MAC, USB 2.0 Device and USB 2.0 OTG via the efficient APS bus. They also share the simple vectored interrupt structure which ensures rapid, real time interrupt response, with low software overhead.
The APS toolchain and IDE (for C and C++) is available to licensees free of charge, and which can be customised and branded for final customer use. Ports of various RTOSs are available such as FreeRTOS, Micrium µC/OSII and µCLinux.
