Embodiment Construction

[0026] The present invention is described in further detail now in conjunction with accompanying drawing.

[0027] It should be noted that terms such as "upper", "lower", "left", "right", "front", and "rear" quoted in the invention are only for clarity of description, not for Limiting the practicable scope of the present invention, and the change or adjustment of the relative relationship shall also be regarded as the practicable scope of the present invention without substantive changes in the technical content.

[0028] like figure 1 As shown, the present invention is applied to the PCIe transport layer, and mainly includes four parts: a compression module, a merge module, a split module and a decompression module. The compression module and the merging module are at the sending end, and the splitting module and the decompression module are at the receiving end. The compression module can compress the header information of the memory write request; the merge module can mer...

Abstract

The invention discloses a system and a method for merging and sending PCIe memory write requests. The system comprises a compression module, a merging module, a splitting module and a decompression module; the compression module can compress packet header information of a memory write request; the merging module can merge a large number of compressed memory write requests into a user-defined information message; the splitting module can split the received user-defined information message into a plurality of compressed memory write requests; the decompression module is capable of decompressing the compressed memory write request into an original memory write request. According to the invention, packet header cells and bandwidth can be saved, and PCIe transmission efficiency is improved.

Description

technical field [0001] The invention discloses a system and method for combining and sending PCIe memory write requests, and relates to the technical field of sending and receiving packets at the PCIe transport layer. Background technique [0002] Many existing applications send many memory write requests with small data on PCIe. These small memory write requests will consume a large number of header cells (header credit) and additional transmission layer, data link layer, and physical layer bandwidth, resulting in a decline in PCIe transmission efficiency. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides a system and method for combining and sending PCIe memory write requests. [0004] To achieve the above object, the present invention adopts the following technical solutions: [0005] A system for merging and sending PCIe memory write requests, including a compression module, a merging module, a splitting mo...
