Abstract
A computer of a pipeline type is provided in which a processing of exchanging data stored in two data storing portions can be performed at a high speed by adding a comparatively simple circuit structure without increasing the operation processing time of an instruction executing portion. An exclusive-OR gate executes the exclusive-OR of the ordinary operation result (ALU operation result) on the E-stage stored in an operation result register and data stored in a bus register, and outputs the EXOR operation result to a selector. The selector outputs one of the EXOR operation result and the ALU operation result stored in the operation result register based on SWAP indication information stored in a register for SWAP instructions.
