Description

technical field [0001] The invention relates to the technical field of interface communication, and specifically provides an FPGA-based multi-protocol communication data exchange device and method. Background technique [0002] Multi-protocol forwarding is widely used in digital communication systems, but the interface types in most systems are single. In a system where multiple protocol modules need to communicate with each other, the traditional method requires the CPU to convert each protocol through the protocol stack, which undoubtedly increases hardware resources and difficulty in debugging. [0003] FPGA (Field-Programmable Gate Array), that is, Field Programmable Gate Array, is a product of further development on the basis of programmable devices such as PAL, GAL, and CPLD. It emerged as a semi-custom circuit in the field of application-specific integrated circuits (ASIC), which not only solves the shortcomings of custom circuits, but also overcomes the shortcomings...
