ABSTRACT:
An information processing apparatus which, when executing a plurality of predetermined units of processing, executes the predetermined units of processing in parallel by a processor by switching between contexts associated with the respective predetermined units. The processing apparatus comprises a plurality of register banks that respectively store the contexts associated with the respective predetermined units of processing, the processor that, after the context switching, executes processing associated with a foreground context, and a save/restore controller that, in parallel with the processor executing the processing associated with the foreground context, saves a background context to memory and restores the context of a unit of processing to be executed the next time from the memory to a background register bank.
