Abstract

An asymmetric multiprocessor capable of increasing a degree of freedom of distributed processing, minimizing a processing load on each processor (CPU), and achieving a large reduction in power consumption by reducing an operating frequency or lowering the power supply voltage. An asymmetric multiprocessor includes a hardware resource mediator that mediates request signals requesting permission to use arbitrary hardware accelerators from CPU cores. A signal processing content selector selects signal processing content of a dynamically reconfigurable signal processor that is connected as a slave A clock skew mediator arbitrarily shifts a clock phase relationship among groups, while clock delay generators delay a clock signal based on a clock skew selection enable signal.
