Hello, I'm using DM642 to process video. However, I found that the frames were captured as YUV422 format by the chip on my DM642 EVM. Then the frames were transformed to be RGB565 format and put into an output buffer. I now utilize the image data in the output buffer to perform desired image processes based on RGB color model. I wonder if the flow is appropriate? Or I'm supposed...

Hi, all Recently, I develop Mpeg4 decoder by using DM642. Video bitstream was transfered from PC throuth PCI to SSDRAM in dm642. The bitstream was a ".avi" file and is of PAL type video. The frame is of 352*288 pixels(CIF type). As we know, to correctly display the video, the output frames should be in speed of 25 frames per second. While the frame rate is a little faster than 25 frames per s...

Hi All, We are doing a project using DM642 processor. In our application we want to store the video data into the HARD DISK of windows XP PC through the PCI of DM642. My question is: 1.Will the video data trasferred directly or wil that be converted to some other form as it has to use PCI? 2.What wil be the interface IDE or SCSI? 3.Will the transfer be serial or parallel? Please clarify my ...

Hi All, I am using XDS560 PCI emulator inorder to debug the DSP code running on DM642. By using Parallel Debug Manager I was able to connect the DSP Board which consists of four DM642's and after that i was able to load my DSP.out file into each DM642 Processor. But While running the dsp code i am facing the following error Error: Error 0x00000022/-1154 Error during: Memory, Execution, ...

Hi , I have purchased DM642 EVM board recently. Is JTAG Emulator must for connecting the PC with the board. I don't have the JTAG emulator with me, can i use 9pin connector(rs-232) and connect the PC with the board. In the case of tms320c6713 dsk ,i used to connect the PC with board using the USB cable provided by the vendor. Why is JTAG Emulator a must in the case of connecting DM642 E

Hi All, I am operating the video port in 8 bit RAW capture mode on DM642. I have used TW2816 Techwell video decoder which is interfaced to video port of DM642. I was able to capture the video, but the video is not synchronized this is due to the lack of sync signals from TW2816. So i have pulled the CAPEN signal as high(VPCTL0 is connected to VCC), so the video port captures the data contionous...

Hi, I have to configure the channel A and B of Video port1 of DM642 (720MHz) EVM, for capture. The Video port1 is connected through TVP5150 Video Decoder on DM642 EVM. I am using "ntsc.pjt" as a reference project. I have made following things to configure, I have enabled DCHNL bit of VPCTL register and DCDIS bit is made 0 in VPSTAT register. capChan2 = FVID_create("/VP1CAPTURE/...

Hi all, I am building a Compact Flash Interface to the DM642. The CF cards can operate in 3 modes: - PC Card memory mode - PC Card IO mode - True IDE mode Does anyone know which of these 3 modes is the easiest to implement for a DM642 interface? I thought I could focus on the easiest mode if someone has already done the g

Hello: Is there a way to tell using any registers if the DM642 internal PLL is locked, and if it is, at what frequency? There is a problem with the input clock causing unexpected behaviour of the EMIF (which runs off the PLL) - and I am wondering if this can be caught using any registers. Thanks ~ka

Dear group, to anyone who has used DM642 on a PCI card and accessed it from a Windows PC using dm642_lib (from ValleyTech, part of EVM642 board): Did you use dm642_lib in a multithread environment? If yes - how? In my application, the DM642-access is implemented in a Win32-dll. Several Windows application use this dll to access the DM642 in parallel. I implemented ressource protection (M...
