Abstract

PURPOSE:To automatically produce necessary data or branched codes and eliminate branching instructions at every data or every branched code, so that the number of words in programs may be reduced, by continuously programing prescribed instructions. CONSTITUTION:An NSET instruction which sets data to a N register 28 is added to an input terminal 11a, and a DINC instruction which increments data is added to another input terminal 11b, and then, the instruction is synchronized with the second basic synchronizing signal phi2 at a gate controlling circuit 12. Also, the DINC instruction is synchronized with the first basic synchronizing signal phi1 at a gate circuit 24 and added to the N register. The DINC instruction is synchronized with the signal phi1 at a counter controlling circuit 17 and the count data are delivered to a counter 21. The output of the counter 21 is added to a selector 22, and the output of the counter 21 is selected when the DINC instruction is given. The data on a data bus 23 are selected when instructions other than DINC instruction are given. The output of the selector 22 is stored in the register 28 by latch pulses from the circuit 24.
