Abstract
PURPOSE: To speed up the execution speed of program, by ending the output of high speed buffer and input preparation and performing parallelly the readout of program and execution.
CONSTITUTION: The high speed buffer 2 for auxiliary memory is provided between the microprogram memory 1 and the program execution hardware 3. Further, the program control signal 6 is received with the memory 1, the next instruction is delivered to the program bus line 4 and inputted to the buffer 2. Further, in the hardware 3, when the execution of instruction is finished, the buffer 2 delivers the next instruction to the hardware 3 via the line 5. Further, when the buffer 2 outputs instruction, the memory content is shifted to the output side and the output and input preparations are finished. Thus, the readout and execution of program are made parallelly, the execution speed of pro-ram can be speeded up.
