Hi all,
we are developing special video processing board.
It uses special image processing routine which is operated by DSP of DM6446.
Our board can drive well ethernet, USB, GPIO, Video input, Video output by ARM , not DSP now.
Past , When I was developing IPTV, I had worked with DSP codec source develpoed by ITTIAM company. It used H.264 decoder.
IXP425 ARM processor and DM642 DSP were using interrupt lines to communicate each other.
But now, We must use DSP function which was developed by ourself, not common codecs.
I know only, These processors use interrupt to communicate . but , I have problem to create interprocessing platform for two processor.
Our project is using simple signal processing routine, it can operate well with simple interprocessor method.
in DSP side, it's processing routine can be run without DSP/BIOS OS, because it is very simple algorithm.
How can I start interprocess ARM and DSP ? Where can I take simple example platform for interprocessing of ARM and DSP?
Best regards,
gslee.
