摘要
此文提出用DSP作为AIS的核心处理器,来进行SOTDMA通信协议处理;介绍了HDLC的组帧和解包、数据传输、时隙分配、UTC定时等的DSP实现方法:以TMS320VC5410 DSP芯片为硬件平台,采用汇编语言进行编程,用CCS5000进行调试,证实这些方法的正确、可行。
Put forward that the digital signal pro-cessor(DSP)can be used in the automatic identification system(AIS) to progress the SOTDMA protocol. Introduced the realization method of the HDLC data packing and unpacking, time slots distribution and UTC timing. To confirm the correct and feasible of these methods, we use TMS320V5410 DSP chip as the hardware, adopt the assembly language to write the programs. Through debug using CCS5000, we get the correct result.
