PURPOSE:To obtain a device where the order of instructions is changed feely, by providing memories, where micro instructions and macro instructions are stored respectively, and a control generating circuit which can access these memories and determines the address an instruction to be executed next. CONSTITUTION:In respect to memories where micro instructions and macro instructions are stored respectively and a control circuit which determines the address of the next instruction, micro instructions and macro instructions are stored in a control memory 10 and a memory 12 respectively. An address control command is sent from the control memory 10 to a micro control order generating circuit 11 to designate the address of an instruction to be executed next, and this instruction is stored in an instruction register and decoder 13 and is decoded and is outputted as a branch address. Control data is sent from the memory 12 to an operating circuit ALU and a register file 14 to designate a macro instruction to be executed next through a selecting circuit 16, and this instructin is stored in a memory address register 15. |
