PURPOSE:To decrease the number of dynamic steps of a program and to improve the processing speed of a computer, by providing a loop counter which counts the number of times of the loop operation of a program. CONSTITUTION:A flag for conditional branch is inputted to a read-only memory 1', whose output is held in an FF2', the output of which is applied as an output address to the memory 1' and also applied to an ROM3' stored with the program. The loop counter 4 is connected to this ROM3' to count the frequency of the loop operation by the counter 4. The counter 4 is cleared by an initial setting signal from the ROM3' to count a signal from the FF2' through a loop counter line up to a specific number, and then the flag for conditional branch is applied from the loop counter output line to the ROM1' to decrease the number of dynamic steps of the program, increasing the processing speed of the computer. |
