A bus protocol command processing device and related method

Abstract

The embodiment of the invention discloses a bus protocol command processing device and a related method. The device comprises N bus protocol command processing modules AXI SLAVE, a sharing command buffer, X memory BANKs and N sharing memories; the AXI SLAVEs are used for receiving N original commands from a bus AXI BUS based on a bus protocol; the sharing command buffer is connected with the AXI SLAVEs; the BANKs are connected with the sharing command buffer; the sharing memories are connected with the BANKs, and M of the N AXI SLAVEs share M sharing memories corresponding to the M AXI SLAVEs. According to the bus protocol command processing device and the related method, by increasing the cmd buffer and the sharing memories in the bus protocol command processing device, parallel processing of all the BANKs cannot be limited by serial characteristics of the AXI SLAVEs when data is read, and the data processing efficiency is improved; furthermore, by arranging the sharing memories, hardware resources of the memories are reduced.

Description

technical field [0001] The invention relates to the communication field, in particular to a bus protocol command processing device and a related method. Background technique [0002] In the last level cache (LLC for short), the bus protocol (AdvancedXtensible Interface, AXI for short) commands will be split according to a certain granularity, interleaved and sent to different cache lines cache banks, such as cacheable commands, or dynamic Storage control (Dynamic memory control, DMC for short), such as the uncacheable command. Since each cache bank / DMC is processed independently, but AXI processes commands serially, it is impossible to efficiently use cache banks / DMCs to process commands in parallel. Contents of the invention [0003] Embodiments of the present invention provide a bus protocol command processing device and a related method, in order to prevent BANK blocking, save memory hardware configuration resources, and improve command processing efficiency.
