METHOD AND APPARATUS FOR WRITING A PORTION OF A REGISTER IN A MICROPROCESSOR

摘要

Method and system for writing data into a register entry of a processing unit is provided. A logic unit issues an instruction for writing result data into a register entry. At least one functional unit coupled to the logic unit receives the instruction and provides partial result data to be written into the register entry and information regarding the partial result data. A logic circuit coupled to the register entry receives the information regarding the partial result data and writes the partial result data into at least one portion of the register entry based on the received information, the at least one portion of the register entry being determined based on the received information.
