Hello, I am using the MATLAB 'actxserver' function to establish a connection to RTDX(for real-time data exchance between MATLAB and a DSP board) and if say 'h' is my activex object, I use invoke(h) to get a list of functions I can use in that interface. There are some functions that have "pointer(variant)" or something similiar as the argument to the function. Anybody know what these are an...

Hi, Soon i will implement a video compression algorithm on DM642. I'd like to recover the compressed data, which will be stored in SDRAM, in order to be able to replay the video on the PC. Can you tell me if Code Composer allows us to recover data stored in external memory and to save them in a file on the PC ? Does RTDX allow to do that ? Could you point me to some example codes ? ...


BIOS 5.31 and HST module

Hello, I read in the latest version of BIOS API manual (SPRU403m) that the HST module will not be supported in future releases. This seemed like a convenient way to communicate with a host processor. Are there other means (within the BIOS framework) of communicating with the host? My understanding of RTDX is that it is used with JTAG. Thanks for any info on this topic. Eknath

Hello, I am using CCS 3.3 and try to use Host Channels (for input, dataflow is Host-> Target). Therefore I created in the BIOS a new HST. Mode is input, bufseq is DDR2, bufalign is 4, framesize (words) is 1 and numframes is 1. The HST uses RTDX, which is enabled. The I try to bind the HST to a file. The file created with the following c-code: FILE *f=fopen("data.dat", "wb"); int

Hello, I writing an application using the full TI kit : Code composer studio, DSP/BIOS,... and i need to know the CPU usage. The TI's DSP/BIOS include an IDL thread which can be used to see CPU usage using RTDX (jtag, debugger...). But the application i made run on a proprety acquisition board. So the idea is to uses this IDL thread in order to monitor the CPU usage. Unfortunatly, the T...
