Monitoring Cache misses

Other Parts Discussed in Thread: SYSBIOS, DM3730

Is there any register or any technique that I can use to monitor cache misses? My goal is to print a message in my application whenever there is a cache miss. I am using SysBios v6.31 and CCS v4.2.3 and C64x+ core.

Thanks,

Rahul

Is this for real hardware or simulator?

I'm not aware of any technique available on the hardware.

For the simulator (depending on which device), there might be some cache analysis tools but I'm not real sure what's available.

This is for real hardware. I am using DM3730 soc and I am working on C64x+ DSP core.

If you do a search of "cache analysis" from CCS help looks like there is some infomation on how this can possibly be setup for some hardware devices.

From a runtime point of view, there isn't a way for this to be detected, another words you cannot at runtime determine if a cache hit/miss occurred and print a statement on a miss.

Also, I think this posts should be moved to a CCS forum since its not BIOS related but more Tools related.
