ABSTRACT:
The present invention is directed to a program control unit which enables a program control to achieve an efficient loop processing which does not immediately follow a loop instruction and which contains a start address and end address. In the program control unit, the start address and end address of a loop processing are stored in a register (start) (7) and a register (end) (8), respectively, in synchronization with a clock t1. The stored data "start" of the register (7) and the stored data "end" of the register (8) are inputted to a comparator (12) and a comparator (11), respectively. The comparator (12) compares the output from a delay program counter (18) with the data "start", and sets a flag f start when the comparison result indicates agreement and otherwise resets it. The comparator (11) compares the output from a delay program counter (18) with the data "end", and sets a flag f end when the comparison result indicates agreement and otherwise resets it.
