Hi The issue of finding execution time is a bit tricky if u r using code composer studio. I've found that the CCS gives a larger-than-actual time estimate. The way I prefer is as follows:(Needs a CRO and some probing) 1)Just before u enter the routine assert HINT by programming HPIC. 2)Once the host clears this interrupt, ur fft code should execute. 3)After the execution of the fft code, again assert HINT. By probing the HINT pin and finding the time difference between HINT going high and HINT going low, we get the actual time taken for execution. regards, satheesh -----Original Message----- From: [mailto:] Sent: Saturday, January 13, 2001 9:25 AM To: Subject: [c54x] execution time Hi All, Pls let me know how to find the execution time to process an fft algorithm in TMS320C542 Dskplus Starter Kit.

Hi all, Even the same thing I also observed as satheesh. But there is a solution for this. Instead of giving 'RUN' use 'MULTIPLE OPERATION' . In this way code-composer will do single stepping, the number of times 'MULTIPLE OPERATION' you have set. This time is perfect, and I have cross checked it manually. rgds, shashi satheesh wrote: > Hi > The issue of finding execution time is a bit tricky if u r using code > composer studio.
