Title: METHOD FOR MANAGING COMPUTATION TASKS ON A FUNCTIONALLY ASYMMETRIC MULTI-CORE PROCESSOR
Abstract:
Method of managing a computation 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) allowing the execution of specialized instructions, comprising the following steps: a) starting the execution of the computation task on a core of the processor; b) performing a tracking of a parameter (QoS) indicative of a quality of service of the computation task, as well as of a number of specialized instructions loaded by said core; c) identifying instants splitting an applicative period of the computation task into a predetermined number of portions (PTS); d) computing costs or gains in quality of service and in energy consumption corresponding to various management options in respect of the computation task; and e) performing a choice of management as a function of the costs or gains thus computed. Computer program product, processor and computing system for the implementation of such a method.
