摘要
设计了一种基于新型浮点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,完成6路模拟量和3路数字量实时采集的同时,实现低成本大容量的非易失数据存储,其浮点运算能力满足导航算法需求,双CAN总线接口可接驳多种上位机,通过片内高速数据交换通道还可扩展高性能DSP阵列。跑车试验表明,该设计用更小的体积和功耗实现了低成本导航计算机系统。
An miniature navigation computer system based on new type floating-point DSP TMS320F28335 is designed to replace similar system on dual-processors. Six channels of analog signal and three channels of digital signal are real-time sampled and saved in a low-cost nonvolatile large memory. The computing capability of floating-point unit can satisfy performance requirements of navigation algorithm. Dual CAN can be shared with several kinds of upper computer. DSP array is constructed by on-chip high speed interface. Ground vehicle test indicates that a lower cost navigation computer svstem with smaller volume and power consumption is realized.
