高层次综合技术在遥测地面站数据处理中的应用

Application of High-Level Synthesis in Data Processing of Telemetry Ground Station

摘要:

针对遥测地面站所接收的遥测数据的数据结构复杂,使用FPGA实现遥测数据处理难度较大的问题,提出了基于高层次综合技术的地面站遥测数据处理方法；相对于传统的RTL实现方式,利用高层次综合技术,在实现同等功能的条件下,能够有效缩短FPGA设计、开发周期；经测试,使用高层次综合技术对遥测数据进行处理,其代码量仅为RTL实现方式的1/10至1/20,代码开发周期缩仅为RTL实现方式的1/4至1/10,且代码运行效率并无明显降低。

Abstract:

The data structure of telemetry data received by telemetry ground station is complex, there are difficulties in processing telemetry data based on FPGA. Thus the High-Level Synthesis technology is introduced. High-Level Synthesis can shorten FPGA design and development cycle compared to traditional RTL implementation when implementing identical functions. Comparing to RTL implementation, the code size about telemetry data processing is only 1/10 to 1/20, the development cycle is only 1/4 to 1/10, and the code execution efficiency is identical.
