Abstract: A computer system and a memory access technology are provided. In the computer system, when load/store instructions having a dependency relationship is processed, dependency information between a producer load/store instruction and a consumer load/store instruction can be obtained from a processor. A consumer load/store request is sent to a memory controller in the computer system based on the obtained dependency information, so that the memory controller can terminate a dependency relationship between load/store requests in the memory controller locally based on the dependency information in the received consumer load/store request, and execute the consumer load/store request.

Abstract: This application provides a signal processing method and a communication apparatus. The method includes: if it is detected that at least one signal feature of each carrier signal in a first combined signal changes, determining, based on the signal feature of each carrier signal, a first clipping noise power corresponding to each carrier signal; and performing clipping on each carrier signal based on the first clipping noise power corresponding to each carrier signal. The signal feature includes one or more of a power, a bandwidth, a frequency, a power spectral density, or a modulation scheme. According to this method, clipping processing is performed on each carrier signal, to reduce a PAPR in an OFDM system. In addition, when the signal feature of each carrier signal changes, an access network device may determine a clipping noise power of each carrier signal based on a changed signal feature of each carrier signal.
