Abstract

PURPOSE:To efficiently execute an operation of an operation processing part, by constituting a device so that an operating instruction based on a timing signal which has detected a pipeline processing stage of an operation processing part is held by the respective instruction holding means for dividing an operation control execution stage into plural parts. CONSTITUTION:In a data processing equipment which is provided with an operation processing part 23 of a pipeline structure, and processes a vector instruction, 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. In this way, an operation of the operation processing is executed efficiently by elevating a transfer timing of instructing information to an operation processing control part of poststage.
