Abstract

PURPOSE: To compose an information processor small-scale hardware by performing easy and regular control without increasing the number of steps of a microprogram.
CONSTITUTION: This processor is equipped with microprogram storage circuit 60 stored with several microinstructions which process operation M by N bytes performs one microinstruction, operand registers 30 to 33 stored with arithmetic result from arithmetic circuit 50, and byte control circuit 70 which generates an address indicating a storage position by an instruction from storage circuit 60 and then supplies it to operand registers 30 to 33. By the address supplied from byte control circuit 70, information supplied supplied from operand registers 30 to 33 is supplied to arithmetic circuit 50. Therefore, control circuit 70 only performs input-output control over registers 30 to 31 regularly and requires small-scale hardware.
