Abstract
This application relates to a method and apparatus for processing a new read-write-operation instruction added to an instruction set to maximize the performance of processing-in-memory (PIM). The read-write-operation instruction performs reading and writing on an operation result of the PIM by returning the operation result of the PIM to a computer system and, at the same time, writing the operation result to a destination address. An instruction processor in PIM includes a response data selector and a finite state machine to process the read-write-operation instruction. The response data selector includes a selector configured to select one of a response data signal and an operation result, and a three-phase buffer configured to allow or disallow response data. The finite state machine of the instruction processor outputs a response permission signal and a response selection signal for controlling the buffer and the selector.
