PROBLEM TO BE SOLVED: To provide an information processor suitable for a real time system and its context switching method. SOLUTION: This information processor for making a processor simultaneously execute a plurality of processing units in parallel by switching contexts corresponding to each processing unit at the time of making the processor execute the plurality of predetermined processing units is provided with: a plurality of register banks for respectively storing the contexts associated with each of the plurality of processing units, the processor for performing processing corresponding to foreground contexts at the time of switching contexts, and a save/restore controller for saving background contexts in a memory, and for restoring the contexts of the processing units to be executed the next from the memory in a background register bank in parallel with the execution of the processing corresponding to the foreground contexts in the processor.
