High-speed data exchange system between 10-gigabit Ethernet and RapidIO protocol based on FPGA

Abstract

The invention discloses a high-speed data exchange system between a 10-gigabit Ethernet and a RapidIO protocol based on an FPGA. A RapidIO gateway splits an Ethernet packet into RapidIO bus mailbox messages. Processing modules in an Ethernet interconnection sub-system are connected through an Ethernet exchange module. The Ethernet interconnection sub-system is externally connected with a RapidIO exchange module through the RapidIO gateway and then carries out data interaction with the processing modules in a RapidIO interconnection sub-system through the RapidIO exchange module. An IP network data packet and a RapidIO protocol data packet are mutually converted in the RapidIO gateway. A RapidIO mailbox message receiving and processing module is used for receiving the RapidIO messages and converting the messages into the Ethernet packet. A 10-gigabit Ethernet packet receiving and processing module is used for receiving the Ethernet packet and converts the Ethernet packet into the RapidIO messages.

Description

technical field [0001] The invention belongs to the technical field of network security, in particular to an FPGA-based high-speed data exchange system between 10 Gigabit Ethernet and RapidIO protocols. Background technique [0002] In the electronic system, the communication links used by each subsystem according to the functional requirements adopt the communication protocol of Ethernet or RapidIO respectively. Realizing the high-speed data exchange of 10 Gigabit Ethernet and RapidIO protocol between the subsystems is the prerequisite for the normal communication work of large electronic systems. Base. In the traditional way, the communication between the Ethernet and RapidIO protocols in each subsystem is independent of each other, or the processor receives the data of these two protocols and performs simple interaction after packet analysis. [0003] The data exchange between the two existing communication protocols adopts a simple interaction after receiving and analyz...

AI Technical Summary

Problems solved by technology

[0003] The data exchange between the two existing communication protocols adopts a simple interaction after receiving and analyzing the processor, and there is a gateway for cross-linking between the two buses, which cannot solve the problem of the data packet format, transmission mode, and routing protocol between the two protocols. The difference between them not only increases the complexity of the system, but also reduces the reliability and real-time performance of the electronic system, which can no longer meet the requirements of unification and real-time transmission and exchange of communication links between subsystems in large-scale electronic systems under the new situation.
