Embodiment Construction

[0015] The technical solution of the present invention will be specifically described below in conjunction with the accompanying drawings.

[0016] Redundant processing flow such as figure 1 As shown, the radar echo data is streamlined by multiple processing nodes through the data distribution interface, and the processed data is sent to sink node 1 and sink node 2 through two SRIO channels, and the sink node is processed through the AB road cross The data flow switches between data processing 1 and 2.

[0017] The node allocation process is as follows figure 2 As shown, the data allocation interface polls the allocation to obtain the busy status information of the processing node. If a processing node is busy, no data will be allocated to the node, and the busy status of the n+1th node is judged. If the node is busy , then assign data to the node, record the node number, otherwise query the n+2th node, if all the nodes are traversed and the status is busy, then assign the ...

Abstract

The invention discloses a chip data redundancy processing method, which comprises the following steps: radar echo data is subjected to line production by a plurality of processing nodes through a data distribution interface, the processed data is sent to a sink node 1 and a sink node 2 through two SRIO channels, the sink node is switched between data processing 1 and data processing 2 through AB-path cross processing data streams, and the data processing 1 and the data processing 2 are switched between data processing 1 and data processing 2; it is ensured that the system does not have a single node and a single channel, each node and channel have redundant hot backup, and the task reliability of the information processor is improved.

Description

technical field [0001] The invention belongs to the technical field of radar signal processing, and in particular relates to a redundant backup technology. Background technique [0002] The domestic chip research and development level is advancing by leaps and bounds. Taking the Huarui chip developed by CETC 14 as an example, it is the first high-end DSP processing chip with international advanced level in China, which meets the needs of high-end processing chips for domestic radar equipment. Some design defects found during the use of the chip have affected the stability and reliability of the product, and it is urgent to solve the shortcomings of the chip from the system architecture design. Contents of the invention [0003] In order to solve the problems existing in the prior art, the present invention proposes a chip data redundancy processing method. In order to achieve the above purpose, the present invention adopts the following technical solutions. [0004] Data ...
