Abstract
A task processor includes a CPU, a save circuit, and a task control circuit. The CPU is provided with a processing register and an execution control circuit operative to load data from a memory into a processing register and execute a task in accordance with the data in the processing register. The task control circuit is provided with a task selecting circuit and state storage units respectively associated with tasks. In executing a predetermined system call, the execution control circuit notifies the task control circuit as such. Upon being notified of the execution of the system call instruction, the task control circuit switches a task to be executed next in accordance with an output from the task selecting circuit. The task selecting circuit selects a task in accordance with an output from the state registers.
