1553 bus network product

Abstract

The invention discloses a 1553 bus network product. The 1553 bus network product is realized by an FPGA and comprises 1553 bus network protocol software and a 1553 bus network protocol logic IP core,wherein the 1553 bus network protocol logic IP core is used for analyzing the 1553 bus data and processing a protocol, and comprises more than one RT module, more than one BC module and one BM module;the RT module uploads a datagram on a 1553 bus to the BM module, and the BC module uploads an error state of a message on the 1553 bus to the BM module, and the BM module transmits data uploaded by the RT module and the BC module to 1553 bus network protocol software; and the 1553 bus network protocol software is used for data transmission and forwarding. The1553 bus network product greatly reduces dependence of the product on a hardware platform, improves the stability, reliability and reusability of the product, and remarkably reduces the development and maintenance cost of the product.

Description

technical field [0001] The invention relates to the field of on-board bus networks of avionics systems, in particular to a 1553 bus network product composed of FPGA logic cores. Background technique [0002] 1553 bus network products are widely used in the aerospace field. The current market demand for 1553 bus network products for miniaturization, low power consumption, low cost, and high reliability is increasing. At present, the design method of FPGA external protocol processing chips can no longer satisfy users. need. Accordingly, there is an increasing demand for the design of the 1553 bus network logic IP core that can replace the protocol processing chip. In addition, in order to realize the application of the 1553 bus network protocol, it is necessary to develop a set of software driver and test environment that can adapt to the network protocol IP. [0003] In summary, the design and implementation of the 1553 bus network protocol based on FPGA includes the design...
