PROBLEM TO BE SOLVED: To save a space of analysis logic and to dispense with reassembly of a hardware circuit whenever the logic is updated by enabling to construct a simple CPU core with high performance on a logical integrated circuit such as FPGA. SOLUTION: A processing to be performed by a control part is simplified since the control part is made to read an instruction and to directly transmit on/off information of each bit to constitute micro-codes to be included in the instruction to registers 25, 28, 29 and a data memory 8 allocated to each bit through control lines L1 to L5 and to control them. Thus, the simple CPU core is constructed on the logical integrated circuit such as the FPGA since the control part is constituted by simple structure. |
