ARINC429在航空航天等领域应用广泛，RS 232是常用的计算机与外部设备接口。作为某军事领域电子系统测试平台的一部分，设计了基于PXI总线的ARINC429和RS 232的专用通讯模块。以DSP和FPGA联合作为控制器，实现通讯模块的PXI接口，基于专用的协议芯片DEI1016实现ARINC429通讯，由FPGA为协议芯片提供时序和数据的缓存FIFO，并在FPGA中集成了RS 232协议编解码。测试表明，该通讯模块能实时可靠灵活地收发数据，实现对被测电子系统多路ARINC429和RS 232总线的测试。

Bus ARINC429 is widely used in the fields of aviation and aerospace. RS 232 is a commonly-used interface be-tween a computer and external devices. A specific communication module for ARINC429 and RS 232 based on PXI bus was de-signed as a part of a military-purpose electric equipment automatic test system. The DSP and FPGA are combined as the control-ler to realize PXI bus interface of communication module. ARINC429 bus communication is realized on the basis of specific pro-tocol chip DEI1016. The time sequence and data buffer FIFO is provided for the protocol chip by FPGA. The RS 232 protocol CODEC is integrated into FPGA. The test results indicate that the communication module can receive and transmit data reliably and flexibly. The testing of multi-channel ARINC429 and RS 232 buses of the electronic system under test was achieved.
