Abstract

PURPOSE:To prevent a program from becoming complicated by providing a read- only memory with a bit for controlling a read counter and by achieving desired-frequency, repetition in a prescribed address of the read-only memory. CONSTITUTION:In a read-only memory 14, a bit for controlling a read counter 11 is provided and when an instruction in some address is executed and an advance to the next address is made, which address the advance is made to is determined by the contents of a condition supplied to a condition selecting means 12 to load a next execution address in an address counter 13, thereby executing an instruction in the address. For repeating an instruction in a prescribed address to a desired frequency, the frequency of repetition from the memory 14 is set in a repetition counter 11, so that counting operation of the counter 13 is stopped, therey permitting the repetition counter 11 to repeat the counting-up operation by a conut-up signal. Therefore, the frequency of repetition is set optionally by being specified from the read-only memory 14, thus facilitating the repetition.
