Hi, when running profiling tests on the "C6414 Device Cycle Accurate Simulator", I get different profile numbers when I exceed the 1MB core memory than when my application and test reside within it. My problem is that that the core-application is approaching the 1MB limit. Is there a way, without having to break up the application and test-code into smaller portions, to not suf...

Hi everybody, I have to calculate MIPS taken for my code. To calculate MIPS, I have a formula ==> MIPS = (Total num of cycles/Total num of Instructions)*CPU_Freq. If the formula is right, then, with the help of profiling in CCS, I can find the cycles taken, but what about the instructions, should I do manually?? Or, is there any way to find it out during profiling itself. Waiting for

Hi everyone, When I profile the same code in simulator(6416 Functional Simulator) and DSK (TMS320c6416), the difference in MIPS(Million Instructions Per Cycle) between the two is 1.0.Hardware board is consuming more cycles (higher MIPS) than the simulator.

Question - I can debug my C6414 target fine, but if I try to use any of the profiling tools like statistics view or cpu load graph, then CCS 3.1 locks up on me and I have to kill it via task manager. Anyone know if there is there some trick to getting these tools to work? i.e. some interrupt that needs to be enabled for RTDX or something? (I am using 4.9 BIOS.) Thanks!
