CCS Profiling - S.Satheesh - Oct 6 6:55:00 2000

Hello, I am using Code Composer Studio Ver1.20 to simulate code written for C5410 DSP. I am finding that the clock count given by the profiler of CCS is very much different from what I expect by manually counting. Is this a bug with CCS? Has anyone faced this problem? Pls help With Regards, SATHEESH.S |

I've found this in the bug list there they say this only happens after a rebuild. - But they are probably refering to a case then running on real hardware. It happens a lot more often than that in the simulator. I know no solution but to run on real hardware such as a DSK. But the result isn't always correct then either but it is at least possible to create and measure an reference function with an oscilloscope and be able to see when to trust the cycle count result or not.
