Do you have any specific parameters for > the coprocessor in mind? In March of 2005, Andrey Filippov reported that he had used a Xilinx Spartan 3 FPGA with theora to design a network camera that could compress the image from a 1280x1024 sensor at 30 fps. http://www.linuxdevices.com/articles/AT3888835064.html According to the Xilinx web site, the Spartan-3E (XC3S1200E) with 1.2M system gates can be purchased for under US$9.00 in quantites of 500K. http://www.xilinx.com/products/silicon_solutions/fpgas/spartan_series/spartan3e_fpgas/index.htm Those price/performance parameters were what I had in mind. It just seems like doing the compression right behind the sensor is the way to go. With a 640x480 sensor, maybe that kind of FPGA could also handle the audio compression? Regards, John Kintree
