摘要:

针对在航天嵌入式软件测试中遇到的将1394总线仿真测试融合到分布式测试系统中的实际需求,提出了一种基于ARM&FPGA架构的1394仿真测试前端系统；在简单介绍了1394总线和分布式测试系统后,设计和实现了1394仿真测试前端软硬件,并基于此前端构建分布式仿真测试系统；经测试,1394仿真测试前端满足1394等时数据包和异步数据包的收发时序要求,并成功应用于某航天器软件第三方评测中。

Abstract:

Analyzing the actual needs of the 1394 bus simulation tests are integrated into the distributed test system in the testing of aerospace embedded software, a front end system of 1394 Simulation Test Based on ARM&FPGA was proposed. After a brief introduction of the 1394 bus and distributed test system, the hardware and software of front End System of 1394 simulation tests are designed and implemented, and then the distributed test system is built. The result of the test shows that the 1394 simulation test front end could meet the sending and receiving timing requirements of the 1394 isochronous data and asynchronous data packages, and successfully applied to a spacecraft software third party evaluation.
