Abstract
PURPOSE: To improve the program processing speed by reading the next command from the memory and shortening the cycle time by the access time of memory while executing a sequence by control command according to the type of execution command of the arithmetic unit.
CONSTITUTION: In case of the control method where the execution command is read out of memory 1 and arithmetic process is executed in operational unit by providing memory 1 where program counter 5 and execution command are stored, the "OR" of control command timing h from sequence logic 6 when the output of decoder 3 is a control command and non-control command timing i when the output of decoder 3 is other than control command is processed by OR gate 7, a signal that advances the contents of counter 5 by one is made and, then, a new execution command is read out in the stage where the execution command is being executed when the control command is neither the memory reference command nor the operation command of counter 5.
