  • Patent number: 11907578
    Abstract: The present disclosure relates to a method for classifying instructions according to the number of operands required for processing-in-memory instruction processing, and a computing device applying same. Efficient instruction processing in a processing-in-memory may include identifying the number of operands required when processing an instruction queuing to be processed, interpreting the instruction queuing to be processed and processing an instruction corresponding to the identified number of required operands. When the number of required operands is 0, the instruction interpretation may interpret the instruction queuing to be processed as a WRITE instruction, and the instruction processing may execute memory writing. When the number of required operands is not 0, the instruction processing may execute memory reading in an internal memory of the processing-in-memory by the same number of times as the number of operands required in the instruction interpreted in the instruction interpretation.
