Abstract

The invention discloses a RapidIO-based high-speed communication method between SoC chips of an on-board system. Six transfer rates are included, based on a RapidIO 3.1 communication protocol, according to market demands, the RapidIO interface of SoC chips is configured with four transfer modes: an AXI bus mode, a DMA transfer mode, a DME transfer mode, and a doorbell mode. The communication method designs an automatic transmission method, according to the amount of data to be transmitted and destination address basic information, the most efficient transfer mode is selected from four transfermodes automatically, that transmission bandwidth is fully utilized, the problem of high speed communication between SoC chips and other connected chip-to-terminal equipment in missile guidance systemis solved, and the requirements of large data volume and small data volume are met. The transmission rate can reach 10.3125 Gbps, and the utilization ratio of transmission bandwidth can be increasedfrom 30% to 52%. The method is suitable for most hardware transmission interfaces on the market.

Description

technical field [0001] The invention relates to a communication method, in particular to a RapidIO-based high-speed communication method between SoC chips of an on-board system. Background technique [0002] Missile-guided high-performance embedded signal processing system has the characteristics of frequent communication between chips and boards, large amount of data, and high real-time performance. In a missile system with multi-core processing, the transmission rate between chips directly affects the internal information and data interaction of the missile, so high-speed transmission between chips is very important. [0003] Missile systems usually require real-time processing of a large amount of image data, and a single processor cannot meet the high-speed real-time processing requirements of large amounts of data. At present, the distributed parallel processing method is widely used in the field of high-speed real-time signal processing. At this time, the transmission...
