ABSTRACT:
A processor system includes a main processor having registers and an instruction decode control unit, and a coprocessor. When the main processor performs an operation in accordance with an instruction, the registers store data to be used for the operation and data obtained by the operation, and the control unit sequentially decodes an instruction, and performs a control based on the instruction. When decoding a coprocessor operation instruction to request the coprocessor to perform an operation, which includes operands designating a type of an operation to be performed by the coprocessor, a first register storing data to be used for the operation, and a second register to store data obtained by the operation, the control unit requests the coprocessor to perform the designated type of operation by using a content in the first register, and causes the second register to store a result of the operation.
