A spaceborne communication device that realizes arp and udp protocol data communication based on vhdl language

Abstract

The invention discloses a space-borne communication device for realizing ARP and UDP protocol data communication based on VHDL language, comprising an Ethernet physical layer synchronization module, an ARP / UDP data analysis module, a parallel CRC check module, an ARP data analysis module, an ARP Learning control module, ARP receiving module, ARP sending and response module, UDP data control module, UDP data analysis module, UDP data receiving module, UDP data sending module and ARP / UDP data sending selection module. The invention uses VHDL language to complete the distinction between ARP protocol data and UDP protocol data, complete ARP application and response to ARP request, and complete receiving and sending of UDP data. The invention has the advantages of common data processing protocols, less resource occupation, good portability, etc., can be applied to various types of FPGAs, is especially suitable for simple UDP message processing, and avoids using complicated protocol stacks.

Description

technical field [0001] The invention relates to the communication field, can be applied to various types of FPGAs, uses VHDL language, uses simple SLICE resources to complete complex UDP message processing and ARP learning process, and avoids using complex protocol stacks to complete UDP message communication. Background technique [0002] As the amount of data processed by satellites continues to increase, ordinary LVDS interfaces have been difficult to meet high-speed interface data transmission. Using high-speed interface bus technology to solve the problem of high-speed interface data transmission, but each high-speed interface bus technology interface is not universal, resulting in In the process of development and testing, many accompanying test equipment need to be redeveloped. The on-board communication device that realizes ARP and UDP protocol data communication based on VHDL language can directly receive UDP data and ARP data sent by the PC, ensuring high-speed data...

[0002] As the amount of data processed by satellites continues to increase, ordinary LVDS interfaces have been difficult to meet high-speed interface data transmission. Using high-speed interface bus technology to solve the problem of high-speed interface data transmission, but each high-speed interface bus technology interface is not universal, resulting in In the process of development and testing, many accompanying test equipment need to be redeveloped. The on-board communication device that realizes ARP and UDP protocol data communication based on VHDL language can directly receive UDP data and ARP data sent by the PC, ensuring high-speed data transmission. The generalization and modularization of interfaces are basically realized, which improves the development efficiency of spaceborne equipment, shortens the development cycle, and reduces personnel investment
