Abstract

PURPOSE:To increase a processing speed of the whole counting device, by providing a stage for counting the plural number of elements in parallel with plural operation stages, and supplying a prescribed previous notice signal to a peripheral equipment when said counting has reached the prescribed number. CONSTITUTION:A system 30 operated by keeping the same pace with an operator is provided in parallel with a pipeline operator, and on the first stage of the system, a counter 31 for presetting the number of elements of a group is provided. In this state, the number of elements, which is preset to the counter 31 is counted down by synchronizing with a cycle clock. By this down-counting, appearance of a state which is preceded by the prescribed number of cycle clocks before the last element of 1 group of elements arrives is detected. Subsequently, a previous notice signal W is formed by the timing of detection, it is sent out to a peripheral equipment, and preparation for executing the prescribed processing is performed to the peripheral equipment.
