PURPOSE:To improve the data processing efficiency by providing an instruction starting the execution of the next instruction without awaiting the end of a program after an execution start address of the program in a processing group is designated. CONSTITUTION:Suppose that the execution of a program by the 1st pro grammable counter 600 is started from a point (a), an instruction group m1 is executed and the processing is transited to an instruction group m2, where an instruction group S2 is started by the 2nd programmable counter 650 as if it were a conventional subroutine call. The counter 600 starts the instruction group S2 in the instruction group m2 apart from the conventional processing and the remaining instruction is executed without awaiting the end of the processing in the instruction group S2 and the processing goes to that for the succeeding instruction group m3. Thus, in applying the processing requiring the instantaneous performance such as sense processing whether or not an edge of an external signal comes is processed in the inner loop thereby execut ing the judging processing in a short circulation cycle.
