Micro-benchmarking extension: access to CPU performance counters

by Saurabh Kumar for Tcl/Tk Community

The goal of this project is to design and implement a Tcl Micro-benchmarking extension with commands to interact with the CPU's hardware counters. We first plan to code an extension in C that works under Linux. Linux's Perf tool that provides access to hardware counters will be used to interact with the OS to get the hardware information.
