Abstract

This article examines a hardware multithreaded microprocessor and discusses the impact such an architecture has on existing software energy modeling techniques. A framework is constructed for analyzing the energy behavior of the XMOS XS1-L multithreaded processor and a variation on existing software energy models is proposed, based on analysis of collected energy data. It is shown that by combining execution statistics with sufficient data on the processor’s thread activity and instruction execution costs, a multithreaded software energy model used with Instruction Set Simulation can yield an average error margin of less than 7%.
