A Non-Intrusive Tool Chain to Debug and Optimize MPSoC End-to-End Systems

Abstract

The complexity of the hardware and software stacks in MPSoC requires software optimization with end-to-end knowledge of the system. We propose a non-intrusive, accurate tool chain which can reveal and quantify slowdowns in low-level software mechanisms. Based on emulation, this tool chain extracts behavioral information (time, contention) through hardware side channels, without distorting the software execution flow. This tool consists of two parts. (1) An online acquisition part that dumps hardware platform signals. (2) An offline processing part that consolidates meaningful behavioral information from the dumped data. Validation of method and tools has been done on GNU OpenMP synchronization barrier when running on a 64-core MPSoC.
