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...

I have a system running that uses the Serial Port interrupt. It is the only interrupt enabled in the system. All processes are launched from the interrupt service routine. There are 4 interrupts spaced about 2.5 usec apart, followed by 10 usec period of no interrupt. Thus we have about 200,000 interrupts/sec. The ISR itself, with overhead for call and exit, has a worst case execution time of ...
