Embodiment Construction

[0024] The present invention is a RapidIO exchange design based on serial RapidIO protocol packet exchange, and adopts the RapidIO exchange chip to construct the RapidIO full interconnection network of the system. Through the cascading of RapidIO switching chips, a star-shaped and double-ring system interconnection topology is constructed to support high-performance pipeline data transmission and star-shaped fault characteristics.

[0025] The system software configuration and monitoring management are in the charge of the CPU end node (main management node), which supports power-on RapidIO system discovery, ID allocation, and routing table initialization configuration. During the system work, the CPU is responsible for the management and monitoring of the RapidIO switching network. The CPU implements real-time online reconfiguration of the working mode, working rate, and routing configuration table of the RapidIO end nodes according to the results of network monitoring or mana...

Abstract

The invention provides a system structure based on Rapid IO (Input Output) protocol packet exchange for meeting high-speed communication of Serial Rapid IO applied by an embedded system and further meeting interconnection communication requirement of the Rapid IO and effectively improving the system performance and the fault-tolerant capability. The system structure based on the Rapid IO protocol packet exchange comprises a plurality of Rapid IO exchange chips; and all Rapid IO exchange chips can be used for constructing a star system interconnection topology structure and a dual-loop system interconnection topology structure; and in a plurality of end nodes in all Rapid IO exchange chips, one end node is set as a Rapid IO main management node of the whole system. The invention has the advantages of simpleness for realization of system hardware, flexibility for software configuration, reliable performance, reconstruction support, fault tolerance, adjustable dynamic flow and configurable scale.

Description

technical field [0001] The invention relates to a system structure based on RapidIO protocol packet exchange. Background technique [0002] RapidIO technology is a high-performance low-pin-count crossbar interconnect technology based on packet switching. Its advantages of high bandwidth, low delay, high efficiency and high reliability provide high-performance internal interconnect communication for embedded systems. a good solution. The characteristics of RapidIO switch interconnection technology determine that its system mostly adopts a switch-based topology, and RapidIO endpoint devices are not directly connected but interconnected through switches. Therefore, the design of RapidIO switching technology becomes the key to RapidIO interconnection communication. [0003] At present, the star system structure based on RapidIO protocol packet switching has been reported, but its software configuration is still immature, and it is still difficult to effectively use the transmi...
