Abstract

This paper introduces a basic mixedinteger-linear model (MILP) to design application-specificheterogeneous multiprocessors (ASHM) allowingimprecise computation of tasks executed ina non-preemptive mode.The proposed model wasused in the development of a genetic algorithm integratedinto the tool set MEGA that uses soft computingtechniques for design of optimal/near-optimalASHMs subject to constraints on performance, costand output-data quality.
