Abstract
PURPOSE: To simplify constitution, by stopping the all pipeline arithmetic units by stopping a clock when the supplying of input data to the lst arithmetic unit stops.
CONSTITUTION: Clock signal generator CLK stops sending out clocks if signals BOK and COK indicating the reception from the VC side are not sent back to B and C operand buffers OB and OC respectively when B operand data and C operand data are requested to vector controller VC while the pipeline arithmetic unit of the array processor is executing vector additon. In the same way, the supplying of clocks from CLK stops if signal AOK is not sent back when the pipeline arithmetic unit requests VC to transfer A operand data in operand buffer OA. Further, ×AOK indicates the that no AOK is sent back, and ×BOK and ×COK are the same.
