Abstract

The invention discloses a network checksum algorithm optimization method based on Feiteng platform. The realization process is as follows: first load 128-bit data into NEON 128-bit registers to reduce the number of cycles; The data in the bit register is divided into 8 pieces of 16bit data to be added in pairs, and when the data stream is processed to a certain length, it is switched to arm64 assembly for processing; and then the 64bit to 16bit algorithm operation is performed. Compared with the prior art, a network checksum algorithm optimization method based on the Feiteng platform of the present invention effectively reduces the delay caused by the checksum algorithm when the network UDP receives data, thereby achieving the purpose of improving the efficiency of UDP packet data transmission, and has the advantages of It has the advantages of independent controllability, originality of realization method and obvious realization effect.

Description

technical field [0001] The invention belongs to the technical field of communication and computer, and in particular relates to a network checksum algorithm optimization method based on Feiteng platform. Background technique [0002] The domestic Phytium series processors are based on the ARM64 architecture, fully compatible with the ARMV8 instruction set, and internally implement NEON expansion instructions. This extended instruction SIMD partly makes up for the weakness of the Phytium processor in terms of CPU frequency, and can improve the speed of data-intensive application memory access and data calculation. Among them, common data-intensive applications include graphics computing, entertainment audio-visual, data verification, etc. [0003] Ethernet is the most common communication protocol standard used by existing LANs today. There are many protocols available in the transport layer. Among them, UDP is widely used in LANs because of its simple structure and low tran...
