Electronic apparatus and storage medium storing load distribution program
Abstract:
An electronic apparatus includes: a clock generation section which generates and outputs a clock of a frequency according to a state; and an MPU and a DSP which, being supplied with the clock generated by the clock generation section, execute processes at a processing speed synchronized with the clock. The electronic apparatus further includes: a load prediction section which predicts a DSP load based on a DSP application to be executed now out of DSP applications installed by being coded for processing by the DSP as well as on a frequency of a clock currently being outputted from the clock generation section; and a load allocation section which allocates part of processes of the DSP application to be executed now to the MPU, based on the load predicted by the load prediction section and thereby makes the MPU execute the part of processes.
