Hi, @Alastair: Thanks a bunch for explaining this so well. I was able to write a simple profiler, and run it. I need to profile the code for branches (branch mis predicts simulation), load/store instructions (for cache hits/miss rate), and a couple of other things and therefore, would need to instrument the code. However, I would like to know if writing the output to a file would increase the
