Abstract

PURPOSE:To obtain a vertical microprogram-controlled device whose processing time is shortened, by providing a basic instruction part, composed of a field for a microprocessor, with a sequence control field in addition to an external controlfield. CONSTITUTION:Microinstructions, each consisting of a basic instruction part for arithmetic control or sequence control and an additional instruction part containing an address selection bit and the 1st address information, are stored in a storage device 2. A microprocessor 1, after executing the basic instruction part, outputs the 2nd address information, indicating the address of a microinstruction to be executed next, to a bus 12. An address generator 3 outputs the 3rd address information on the address of the microinstruction to be executed next according to the 1st address information, and an address selecting circuit 5 selects the 2nd or 3rd address information to send the address of the next executed instruction to the storage device 2.
