APPLICATION PROFILING

摘要

A system and associated methods are disclosed for profiling the execution of program code by a processor. The processor provides an instruction set with special profiling instructions for efficiently determining the bounds and latency of memory operations for blocks of program code. Information gathered regarding the bounds and latency of memory operations are used to determine code optimizations, such as allocation of memory for data structures in memory more local to the processor.

主权项

1. A processor comprising:
circuitry for implementing an instruction set of the processor; and circuitry for implementing a register file; wherein the register file provides operand inputs for instructions of the instruction set; and wherein the instruction set comprises a profiling instruction that receives a first input and a second input from the register file and a third input either from the register file or from a special register whose value was set by a previous instruction.
