Domestic FPGA device-based realization of 1553B bus module

The invention discloses domestic FPGA device-based realization of a 1553B bus module. The 1553B bus module comprises a data communication interface chip, an FPGA chip and a 1553B bus protocol chip B61580, wherein the FPGA chip is in charge of processing bus data output by the 1553B bus protocol chip B61580 and sending the bus data to external other products for performing data processing through the data communication interface chip. Internal logic of the FPGA chip adopts top-down design; and logic function modules include a top layer module, an ACE read-write interface module, an initialization module, a protocol processing module, a user function module and an interface management module. The deficiencies of complex scheme composition and inflexibility of a conventional scheme for realizing the 1553B bus module through a DSP, a CPLD and the 1553B bus protocol chip are made up for. 本发明种基于国产化FPGA器件实现1553B总线模块，包括数据通信接口芯片、FPGA芯片、1553B总线协议芯片B61580；FPGA芯片负责处理1553B总线协议芯片B61580输出的总线数据，然后通过数据通信接口芯片发送给外部其他产品进行数据处理。所述
