Problems solved by technology

At the same time, because the channel health status of the UM-BUS bus is based on node-to-node, this makes it impossible to use the two-dimensional channel health status table form in the master and slave communication nodes in the bus monitoring system, otherwise, the monitoring system cannot satisfy any two The organization's requirements for listening to communication packets between communication nodes

specific Embodiment approach

[0032] Based on the operating principle of the above-mentioned UM-BUS bus and bus monitoring nodes, a specific implementation of the channel health state recording device of the present invention is as follows:

[0033] In the bus monitoring system, set such as Figure 5 A channel health state recording device shown includes a channel detection and identification module, a row and column mapping module, a three-dimensional channel table memory, a channel data organization module and a communication data buffer memory. The channel detection and identification module monitors the channel detection process on the bus at the MAC sublayer, and generates source node numbers, target node numbers and channel health status words for channel detection. The row-column mapping module reads and writes the three-dimensional channel table memory according to the request of the channel detection and identification module and the channel data organization module. The channel data organization...

Abstract

A channel health state recording device of a dynamic reconfigurable bus monitoring system is characterized by comprising a channel detection and recognition module, a row and column mapping module, a three-dimensional channel table storage device, a channel data organization module and a communication data buffer storage device, and channel health states of pairwise nodes on a dynamic reconfigurable bus are stored and managed according to channel health state storage tables of three dimensions including row nodes, column nodes and channels.

Description

technical field [0001] The invention relates to a channel health state recording device in an embedded system bus monitoring system, in particular to a channel health state recording device in a dynamically reconfigurable bus. Background technique [0002] The dynamic reconfigurable bus (UM-BUS) is a high-speed serial bus based on M-LVDS bus topology defined for high-reliability embedded applications, such as figure 1 As shown, it adopts a bus-type topology structure, supports direct interconnection of multiple nodes, and can use up to 32 channels to transmit data concurrently. If some channels fail, the bus controller can detect them in real time, dynamically allocate data to the remaining effective channels for transmission, realize dynamic reconstruction, and dynamically fault-tolerant communication failures. [0003] The communication protocol model of UM-BUS bus is as follows: figure 2 As shown, from top to bottom are the processing layer, data link layer, and physic...
