Abstract
A processor core for realizing efficient operation processing by connecting an extended arithmetic unit to its exterior and a processor incorporating such a processing core are provided. The processor includes the processor core, a data memory accessed by the processor core, and the extended arithmetic unit connected to the exterior of the processor core for processing a particular instruction. The extended arithmetic unit executes an arithmetic operation by using arithmetic operation data retained in a register file in the processor core, and directly outputs an arithmetic operation result to the processor core. Then, the processor core saves the result of the arithmetic operation executed by the extended arithmetic unit and inputted therefrom in the register file in the processor core.
