Abstract

PURPOSE: To make it possible to get rid of necessity of the procedure on the memory, performing the branch of a sequence program by the instruction by which the execution control flip-flop is operated.
CONSTITUTION: The instruction which has been read out from the memory is decided in the instruction decoder 1 whether it is the F.F control instruction or not, and a signal is output to the F.F control sequential circuit 2 or the ordinary instruction sequential control circuit 4. The F.F control instruction executes the F.F control by the F.F control sequential circuit 2. The ordinary instruction changes the operation by the status of the execution control F.F3. In case when the status =0, the instruction is executed, and on the other hand, in case when the status =0, the instruction is not executed but is bypassed. The execution control F.F3 is set by the F.F control instruction or an output of the 1 bit accumulator based on the result of operation.
