<p>PURPOSE:To make it possible to execute continuous instructions by avoiding waste of time, by performing the operation by the clock frequency which is suitable for each execution cycle. CONSTITUTION:A digital signal 8 according to the execution time is output to the D/A conversion circuit 5 from the decoding circuit 4, corresponding to classfication of the instruction 7 which is output from the control circuit 1. An optimal clock pulse 9 to the execution cycle based on the above digital signal is generated in the V/F conversion circuit 6, and it is provided to both the control circuit 1 and the operation circuit 2. Thus, waste of the execution time can be avoided by means of execution of the clock frequency which is optimal to each execution cycle.</p> |
