Filed: 1989-10-06
Abstract: PURPOSE: To improve efficiency in the operation of a CPU provided with a multi-functional unit by providing an instruction cache provided with two instruction areas and a first (second) processor for receiving the instruction of a first (second) type from the instruction cache for the processing of data applied to the first (second) processor. CONSTITUTION: The instruction stored in the even-numbered section 56 of the instruction cache 54 is received by a multiplexer 64 for selectively supplying the instruction from the even-numbered section 56 or odd-numbered section 58 of the instruction cache 54 to an integer numbered processor 66 and an FP processor 62 when the instruction is received from the even-numbered section 56 by the integer numbered processor 66. The instruction of the odd-numbered section 58 is stored in a prefetching register 70. Since the instruction generated as a result is received from the prefetching register 70 by the integer numbered processor 66, a program counter register 74 is increased not for 8 but for 0 and thus, the transfer to the instruction cache 54 of a new instruction is inhibited. Thus, the efficiency of the CPU is improved.
