A processor comprising fetch logic adapted to fetch a set of instructions from memory, the set comprising a subset of instructions. The processor further comprises decode logic coupled to the fetch logic and adapted to process the set of instructions, and a clock coupled to the decode logic. When processed, an instruction from the set causes the clock to increment a counter external to the processor while the subset is processed. A status of the counter is manipulated to determine an efficiency level pertaining to the subset of instructions. |
