Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0028] Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless expressly stated otherwise, may be replaced by alternative features which are equivalent or serve a similar purpose. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.

[0029] Such as Figure 5 As shown, a typical dynamic routing of radar data in this specific embodiment is taken as an example for specific description. The intermediate frequency data is sent to the detection processing module after the A / D conve...

Abstract

The invention provides a data dynamic routing system and method based on a RapidIO message mode. A subscription and publication mechanism is adopted, an application component declares the required subscription or publication data type through a client agent, and a service agent instead of the application component itself decides where the data come and go. The system and method are mainly characterized in that information is irrelevant to a device address and is identified based on content, data subscription or publication can be achieved simply by identifying the data type, and a source address and a target address are not needed. Increase and decrease of the number of communication devices do not affect the operation of the system. Therefore, by the adoption of the data dynamic routing method based on the subscription and publication mechanism, middleware used for processing resource virtualization is obtained and located between the application component and hardware, a data receiving and sending interface provided by the middleware is called by an application program based on a total exchange RapidIO network, and then transparent data transmission between two nodes is achieved.

Description

technical field [0001] The invention relates to a data dynamic routing system and method based on RapidIO message mode, in particular to a RapidIO message mode data dynamic routing system and method suitable for RapidIO protocol. Background technique [0002] RapidIO technology is a high-performance, low-pin-count, packet-based interconnection architecture, one of the most commonly used transmission protocols that comply with the OPEN-VPX standard, and is designed to meet the needs of high-performance embedded systems An open interconnect technology standard. There are two data transmission modes provided by the RapidIO transmission protocol: message transmission mode and DMA transmission mode. The message mode is similar to Ethernet data packet transmission, suitable for data mutual transmission between multiple nodes, the advantage is that the transmission is flexible, and the disadvantage is that the processor needs to respond frequently to interrupts in the message mode...
