i have the following queries related to TI's DM642 DSP Eval Board. I need to process 640 x 480 x 24 bits of data at @30fps.The DM642 is 600 MHz processor.The process involves compression and decompresion which we want to do realtime. The compressed data needs to be written to HDD. a)does DM642 has enough internal or external memmory to handle this kind of data.if i use exterenal memory,th...

I am using TI DM642 EVM card in development but in my prototype board I am making, I want to bootload the dsp from a host processor MPC8343. Could some body give me inputs (links) on connecting DM642 to MPC8343. What are the things to watch out for. Any open source available so that I can port it to DSP? Thanks in advance! Dave

Hi I am involved in custom made TI DM642 board development, in which DM642 will be host booted. The custom part comes where the EEPROM used to configure the PCI on reset (on DM642 EVM) is not present. I am interested in knowing the procedure to follow for DSP initialization process. I understand the following should be the approach. 1) PCI will be configured by host when the DSP is held in re...

Hi, I am having difficulties trying to flashburn led.hex (created from led.out) onto DM642 EVM board. From my understanding, it is only after the FPGA is programmed via the fpga_loader program that I will be able to modify the FPGA Flash Page Register to boot my application code from PAGE1. So if I were to flashburn my application onto DM642 EVM board,I would have to: 1.) flashburn my...

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 thing work? How does it communicate status to the calling function? I assume this makes for a much qu

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 users). I know that the data flow itself its a tough job, but I need to start somewhere... ...
