Abstract

An algorithm in a multi-core processor having a plurality of cores for deciding processing allocation to each core to distribute the processing load thereof, and an efficient processing allocation algorithm simplified for software engineers are established. In order to achieve the above processing load distribution, the multi-core processor includes a plurality of basic modules divided into minimum configuration units, each having a uniform input/output format interface, so as to perform required processing contents in the overall processor. As an initial allocation, the above plurality of basic modules are allocated in distribution to the above plurality of cores, and subsequently, based on functional information of each core, the above plurality of initially allocated basic modules are relocated either periodically or at appropriate timing.

Dependent claims

A processing load distribution method in a multi-core processor having a plurality of cores, comprising:

forming a plurality of basic modules, including processing contents required for the overall processor being divided into minimum configuration units each having a unified input/output format interface;
as initial allocation, allocating in distribution the plurality of basic modules to the plurality of cores;
and
subsequently, based on functional information of the each core, relocating the plurality of initially allocated basic modules either periodically or at appropriate timing.
