ABSTRACT:
Machine language instructions corresponding to sequence instructions that are stored in a first memory are stored at addresses of a second memory corresponding to operating codes of the sequence instructions, and a processing unit executes a sequence control by the instructions fetched from the second memory. A jump instruction with non-designated jump-to address is stored in the second memory. Following fetching of the jump instruction from the second memory, the processing unit fetches the sequence instruction to be next executed from the first memory, and the operation code of that sequence instruction is transferred to the processing unit as a jump-to address of the jump instruction.
