We are trying to bring up an new board that contains a TMS320VC33 dsp. After power-up the VC33's H1/H3 clocks are static and the dsp is in a locked up state. TI does have an application note (sgua001c) that describes this behavior in older DSP's. On power-up the dsp would randomly ge

Hi, I am using TMS320VC33 in MCBL mode.But till now we haven't done any boot loader programs, as we are in the initial stages of programming.We are simply writing some code for adc, dac etc for testing purposes.Initially it was fine. But nowadays we find some kind of degradation in the performance of DSP in the sense that,after we run the program twice or thrice the dsp stops responding.hard...

Hi Dani, => Matrix multiplication in ASM, is in the matlib.exe file. This code (is more like a vector library, has several functions) is from TI. The matrix multiplication assumes the matrices are stored in row wise. I used this code.
