Abstract：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.
Key words： strapdown inertial system; DSP; FPGA ; HPI
