摘要:

为了解决实时实时遥测数据挑路及浮点运算在FPGA上实现难度较大的问题，设计了一种基于MicroBlaze的测控终端数据处理模块；测控终端数据处理模块利用FPGA嵌入式处理器实现了复杂遥测数据的挑路及浮点运算，同时利用FPGA的动态部分重配置技术实现了遥测数据挑路的在线配置功能；测试表明该模块可以实现对1553B等具有复杂数据结构的遥测数据进行处理，并能够实现20帧/秒以上的处理速度；测控终端数据处理模块可以实现很多以往需要ARM或DSP才能够实现的复杂遥测数据处理功能。在不增加系统硬件成本的情况下，有效提高了系统的集成度和设计灵活性。

Abstract:

According to the difficulty in real-time telemetry data picking-up and floating-point calculation based on FPGA, a TT&C terminal data processing module is developed based on MicroBlaze. The module uses FPGA embedded processor to realize complex telemetry data picking-up and floating-point calculation, and uses dynamic partial reconfiguring technology to realize on-line configuration about telemetry data picking-up. The test result shows that this module can process complex telemetry data such as 1553B, and can achieve 20 frames per second processing speed. This module can realize a lot of complex telemetry data processing functions that need ARM or DSP in the past. The system integration and design flexibility are improved effectively without increasing hardware cost.
