Abstract

PURPOSE:To prevent a drop of an advance processing efficiency, by calculating an address to an object instruction of an address qualification register by an operator, and exeucting an advance processing continuously, in a pipeline computer for taking in advance an instruction and a data. CONSTITUTION:An operator 21 to which a simple hardware has been added is introduced to an address adder of an instruction advance processor, the advance processor executes a change of an address qualification register, and its object instruction is selectively executed so as to be high in its appearance frequency and available due to introduction of the operator 21, therefore, it is possible to evade a delay of processing due to decision of contents of the address qualification register in case of calculating an address, by adding a small quantity of hardware, and to process a flow of the instruction at a higher speed.
