摘要

摘要: 为使自主水下航行器(AUV)导航计算机成本、功耗和体积达到最低, 设计了一种基于TI公司新型数字信号处理器(DSP)——TMS320F28335的小型导航计算机, 取代以往基于双处理器结构的同类系统, 其浮点运算能力可满足导航计算要求, 同时采用片内的6路A/D转换器, 3路异步串口, 2路控制器局域网(CAN)总线等资源完成数据采集和通信功能, 外扩一片非易失性NAND FLASH实现大容量数据存储, 高速数据交换通道可用于扩展高性能DSP阵列。仿真结果表明, 在规定的周期内, 系统可完成数据采集、接口通信、导航解算、数据存储等任务。该设计用单片处理器和最少的外围芯片数量实现了高性能的导航计算机系统。

Abstract: To realize lower cost and power consumption，and smaller volume, a miniature navigation computer system based on new type of floating-point digital signal processor(DSP)——TMS320F28335 is designed to replace similar system on dual-processors. The computing capability of the floating-point unit can satisfy the performance requirements of navigation algorithm. System functions of data collection and communication can be achieved with on-chip six-channel A/D converter, three asynchronous serial interfaces, and dual controller area network (CAN) buses. Data can be saved in a off-chip low-cost nonvolatile large memory, and a DSP array is constructed via the on-chip high speed interface. Simulation results indicate that the system functions of data collection，communication and navigation calculation can be accomplished in one cycle time, and the high-performance navigation computer system is implemented with minimum number of chips.
