Abstract: This application relates to the field of communications technologies, and in particular, to a management and dispatching apparatus, system and method based on a SAS. The apparatus communicates with a device in a SAS domain based on an upper-layer protocol request. A list management module manages, in a manner of a list, pending input and output information and device information that are obtained based on the upper-layer protocol request. After there is an idle SAS channel, the apparatus obtains the pending input and output information and the device information in the list by indexing the list. A DMAC on the SAS channel performs frame interaction with a corresponding device in the SAS domain based on the pending input and output information and the device information. In this application, a pending task is managed by using a list, and centralized dispatching is implemented, thereby reducing internal resource overheads.

Abstract: A data processing method and system and relevant devices are provided to improve the processing efficiency of cores. The method includes: storing received packets in a same stream sequentially; receiving a Get_packet command sent by each core; selecting, according to a preset scheduling rule, packets for being processed by each core among the stored packets; receiving a tag switching command sent by each core, where the tag switching command indicates that the core has finished a current processing stage; and performing tag switching for the packets in First In First Out (FIFO) order, and allocating the packets to a subsequent core according to the Get_packet command sent by the subsequent core after completion of the tag switching, so that the packet processing continues until all processing stages are finished. A data processing system and relevant devices are provided. With the present invention, the processing efficiency of cores may be improved.
