Abstract: A power transmitting unit (PTU) for wireless power transmission (WPT) includes a communication transceiver and a power controller. The communication transceiver connects a communication link with at least one power receiving unit (PRU) through legacy communication and exchanges parameters necessary for the WPT through the connected communication link. The power controller is configured to transmit, to the PRU, a PTU beacon containing information about a dedicated power slot (DPS) allocated to the PRU in a super frame including a plurality of DPSs, to receive a PRU beacon from the PRU, to extract a phase difference between a plurality of antennas by analyzing a continuous wave (CW) of the PRU beacon, and to transmit power to the PRU in the allocated DPS in consideration of the phase difference.

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.
