ABSTRACT:
An information processing unit has a system bus that connects devices configuring the information processing unit. An arbiter performs arbitration related to use of this system bus, and a clock control circuit controls the clock to be supplied to the devices. The clock control circuit can make a bus request to the arbiter and executes a clock switch or clock halt after being granted use of the bus by the arbiter.
