摘要
本系统由TI公司TMS320C6713和TMS320VC33双DSP作为核心,采用模块化设计方法,双DSP分别实现导航计算及微惯性测量单元(MIMU)信号的高精度数字化;FPGA主要实现输入输出等外围接口扩展、数据缓存、系统通讯及控制、时序控制等功能。导航计算和MIMU信号数字化任务在不同的DSP中完成,有效提高系统精度,更好满足系统实时性要求。实验结果表明:系统实时性较高,精度达到要求,降低了系统功耗和成本。
The navigation computer system :is designed based on dual DSPs and FPGA.In the system,the navigation algorithm and the digital of MIMU is separately executed in the core of-DSP chips TMS320C6713 and TMS320VC33 which are produced by TI,and FPGA which performed the signal acquisition,expanding muti-UART and buffering data.By the way of modularize design,it is effective for the precision of system to improve. The experiments prove that the system work in real time,with higher precision,lower power and cost.
