Abstract

PURPOSE:To increase a processing speed of an operation processing means of a pipeline structure, by constituting a device so that instructing information to the same instruction can be overlapped and held by the respective instruction holding means for dividing an operation control execution stage into plural parts. CONSTITUTION:An operation control execution stage in an instruction control device is divided into two, an instruction is set to an EW stage register 10 by a timing signal of a counter 12 having a timing counting circuit, and by a timing signal of counters 15, 18 having an element counting circuit, instructions which have been set already to an ER register 8 and an EW register 10, respectively, are erased, and the next instruction is set. For instance, between time t1'-t2' and between t3'-t4', the instructing information is overlapped to the registers 8, 10 so that it can be held. In this way, in case of a lot of elements to be processed, the operation processing speed is increased by removing an idle state of the operation processing part of a pipeline structure.
