Concurrent processes on the DM642?

I've been looking at similar sourcecode to some of the stuff I'm trying to do on the DM642 (video in -> process - > out) and noticed that in some functions there seems to be some kind of concurrent processes - ie code within a 'while(1){...' loop that only captures video. How does this kinda ...

DM642 continous dataflow on Videoport

Dear all, Is there someone out there who has tried to continuously capture data using the Videoport of a DM642 ? (No gaps, nor zeros in dataflow, just as a continuous stream of data using the build in FIFO as a buffer for internal non-continous data processing) Is this possible ? ...

Re: Flashburn on DM642 EVM board

Can the DM642 handle lossy JPEG at 1024x768, 30 fps ?

Hey all... Can a DM642 (or a DM643) can handle lossy JPEG compression at 1024 x 768, YUV 8 bit 4:2:2, at 30 fps ? Surely can do D1. But SVGA ? If yes, will it do even at 500 Mhz ? For example, a Blackfin most probably can't handle that, even the dual core (from comments from some us...

Re: fastest DSP?

I think TI's 1 GHz 6414T would be the fastest though feel free to jump in if someone knows of a faster one. If you need PCI then the 6415T is also 1 GHz but with PCI too. TI also has the DM642 which uses the same 64xx core but has high speed video ports, integrated ethernet mac, and PCI. Th...

DM642 CPU Load Function

Hello, I wanted to find out a way to check CPU load using an API in my C code. I use CCS 3.1 and DM642 DSP.
