摘要
在开发某新型微小型组合导航计算机中,采用CPLD和DSP相结合的方式,提出了一种2片DEI1016芯片并行工作的方案并实现。两芯片共构成2收4发6路429通道,采用中断方式并行高速运行。实测结果表明,采用文中设计的软硬件模块,429通道传输数据稳定可靠,且传输效率高。
This paper presents a realization of concurrent working of two DEI1016 chips using the CPLD and the DSP in the developing of a new kind of micro navigation computer. The two DEI1016 chips include the total of 6 429 channels, 2 transmitter channels and 4 receiver channels, which work concurrently and efficiently in interruption mode. The result of the test shows that the 429 channels using the hardware and software presented in this paper can work stably and high -efficiently.
