Abstract

PURPOSE: To increase the processing capability of the entire computer, by performing the data processing and status processing with the pipeline system and by shortening the machine cycle of computer, through the provision of the register memorizing the controlled data and a part of the microprogram with the program.
CONSTITUTION: The operation unit 12 is controlled with the microprogram output from the pipeline register 11 for micro program, it is set to the register 18 together with the internal status information 13 from the operation unit 12, output 14 from the operation unit 12, condition code 15 of the input and output unit, and present status information 16 and further, the control signal 17 being one field of the program determining new status. Further, in the next machine cycle, new status information is produced with the logic circuit 19 by using the information of the unit 18. Further, the data processing and the status processing are made with the pipeline system.
