Measuring clock in C6701 EVM - baud_haryo_prananto - Jan 8 7:32:00 2004

I am using C6701 EVM in PCI slot operation. I want to know how can I
measure the clock working in the EVM. Can I know the clock speed
realtime?

I am creating data acqusition system from webcam to DSP but I find it
very slow. I can't believe that the EVM works in 100 MHz as I set in
the DIP Switch.

Thank you for any help,

Baud Haryo Prananto,
 
A few comments...
1. Usually when I find my "DSP runs slow", I set a couple of breakpoints and count the number of clocks - the number usually seems very high and is sometimes caused by doing something in C that is very convinient and slow.
2. Make sure that you use your memory wisely - Internal RAM is the fastest, then SBSRAM and then SDRAM.
 
regards,
mikedunn
