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

摘要

A method of managing a computing task on a functionally asymmetric multi-core processor comprising a plurality of cores (PC1 - PC4) at least one of which comprises at least one hardware extension (HW1, HW2) for executing instructions characterized by the steps of: a) starting execution of the computation task on a processor core; b) tracking a parameter (QoS) indicative of a quality of service of the computing task, as well as a number of specialized instructions loaded by said core; c) identifying times that split an application period of the calculation task into a predetermined number of portions (PTS); d) calculate costs or gains in quality of service and in energy consumption corresponding to different management options of the calculation task; and e) making a management choice based on the costs or gains thus calculated. Computer program product, processor and computer system for implementing such a method.
