双DSP结构的捷联控制与解算系统设计

The system design of strapdown controlling and solution system based on the structure of double DSP

设计了基于双DSP结构的捷联控制与解算系统,该系统以高性能的浮点处理器TMS320VC33作为捷联系统实时解算的核心,以TMS320VC5402作为通道控制、数据采集的控制核心,并结合FPGA的组合逻辑和时序逻辑,构成了高集成度的嵌入式系统。该系统具有采样速度快、浮点处理精度高、稳定性好等特点,可以充分满足捷联导航系统的要求。

The strapdown controlling and solution system based on the structure of double DSP is designed. This system includes high-performance floating point processor TMS320VC33,which acts as real-time solution core of strapdown system, as well as TMS 320VC5402,which services as the core to be master of access controlling and data acquisition. This system is a kind of embedded high-integration system which has FPGA assembled and scheduling logic. The system has the characteristics of fast sampling, high precision of floating point processing, stability, and etc. It can fully satisfy the requirements of strapdown system.
