METHOD FOR MANAGING COMPUTATION TASKS ON A FUNCTIONALLY ASYMMETRIC MULTI-CORE PROCESSOR

摘要

A method for managing a computation task on a functionally asymmetric multi-core processor includes a plurality of cores at least one of which comprises at least one hardware extension for executing specialized instructions, comprising the following steps: a) starting the execution of the computation task on a core of the processor; b) monitoring a parameter indicative of a quality of service of the computation task, and at least a number of specialized instructions loaded by the core; c) identifying instants splitting an application period of the computation task into a predetermined number of portions; d) computing costs or gains in quality of service and in energy consumption corresponding to different management options of the computation task; and e) making a management choice according to the costs or gains thus computed. Computer program product, processor and computer system for implementing such a method are also provided.
