A message processing method and apparatus

The invention discloses a message processing method and a device thereof, comprising the following steps: an accelerator sends a consistency write request to a consistency system interconnected bus unit; the coherence system interconnect bus unit confirms whether the corresponding data of the coherence write request is in the cache of the CPU, and the corresponding data of the coherence write request performs coherence processing when the cache of the CPU is in the cache; after completing the consistency processing, the CPU reads the corresponding data from the memory. The application can savethe CPU overhead of maintaining cache consistency and effectively improve the speed of message processing. 本文公布了种报文处理的方法及装置，包括：加速器向致性系统互联总线单元发送致性写请求；所述致性系统互联总线单元确认所述致性写请求的相应数据是否在所述CPU的缓存，所述致性写请求的相应数据在所述CPU的缓存时执行致性处理；在完成所述致性处理后，所述CPU从内存读取相应数据。本申请能够节省CPU维护cache致性的开销，有效提高报文处理的速度。
