摘　　要：针对东南大学研制的嵌入式MIMU/GPS紧组合导航系统,研究了基于DSP和FPGA的组合导航计算机数据控制和传输。组合导航计算机由DSP、FPGA以及两片MCU等组成,DSP进行导航计算,FPGA负责外部数据的控制和准备,一片MCU实现GPS控制和解码,另一片MCU传递GPS数据和负责上位机通讯。嵌入式MIMU/GPS紧组合导航系统试验结果表明,MCU及DSP数据部分的控制和传输实时性好,能满足DSP对外围大量数据的需求。Based on the embedded MIMU/GPS tightly coupled integrated navigation system developed by southeast university,the paper realized the platform data control and transmission for DSP and FPGA.Navigation computer is made up of DSP,FPGA and two slices of MCU.DSP is for navigation calculation,and FPGA is responsible for the preparation of external data.Two MCUs are used to alleviate the control.One is only for GPS control and decoding,another is not only for transmission of GPS data,but also for the PC communication.Test results show that the system can satisfy the needs of large amounts of data and has good real-time performance due to good control and transmission of MCU and DSP.
