ARM Cortex-A8: How to measure cache utilization?

Question

Hi Guys,

I have a Freescale's i.MX515EVK, an ARM Cortex-A8/Ubuntu platform with me, unfortunately the Linux kernel on the board is not supporting some of the well known profilers such as Oprofiler or Zoom Profiler(Zoom supports ARM processors, but it internally, uses Oprofiler driver) which give very detailed reports about the cache utilization.

Cortex-A8 has 32KB Instruction and Data caches and a 256KB L2 Cache. Currently when my image processing algorithm is running, I'm totally blind about their usage.

Are there any other methods, other than using profilers to find out cache hits and misses?
