A high-speed communication method that can cross FPGA platforms

Abstract

The invention discloses a high-speed communication method that can cross FPGA platforms. The method includes: connecting different FPGAs through physical high-speed connection lines; establishing channels based on different FPGAs and performing data synchronization verification; performing data transmission through the channels . The invention adopts high-speed interface self-adaptation and can ignore the rule of FPGA sending serial. As long as the two FPGAs can ensure the electrical performance and serial rate to meet their respective sending and receiving performances, the IP can be used to transmit data seamlessly and losslessly. Thereby reducing programmers' unnecessary high-speed interface research on FPGAs from different manufacturers. Moreover, the unified interface mode greatly improves the efficiency of transplantation between different FPGAs.

Description

technical field [0001] The invention belongs to the technical field of computer communication, in particular to a high-speed communication method capable of crossing FPGA platforms. Background technique [0002] With the development of FPGA (Field Programmable Gate Array, Field Programmable Gate Array), the demand for FPGA is getting higher and higher, and with the product iteration of FPGA, the excellent characteristics of its high-speed interface are gradually discovered by everyone. Now two major FPGA manufacturers: Intel and Xilinx have both broken through the speed of 20G, and everyone also likes to use the chips of the two companies at the same time to make various products. [0003] Usually FPGA manufacturers will provide their own simple high-speed communication IP, these IP users are very convenient to use, only need data clock, data input and data valid bits. [0004] However, there is no good simple protocol for FPGA communication between different manufacturers....

Problems solved by technology

[0004] However, there is no good simple protocol for FPGA communication between different manufacturers. When communication is required, more people will choose general protocols such as 10G Ethernet, SAS or SATA for connection, and these connection methods often require a fixed connection speed and more complex configuration

[0005] Therefore, when high-speed communication is required between two chips, a mature and reliable simple high-speed data communication IP is needed for logic developers to develop, and there is no such IP in the Chinese IP market for the time being.
