| 摘 要： | 为了减小捷联系统的体积，重量和功耗，研制了一种主从式紧耦合双处理器结构的导航计算机。以数字信号处理器（DSP）作导航算法处理机，以单片微控制器作I／O接口处理机，二以互中断高速并行接口相联，软件采用主从流水线协议。双机协同流畅，处理速度快，满足了一些捷联系统对导航计算机在数据吞吐和处理能力以及体积、重量、功耗诸方面的要求。

| Abstract: | To reduce the size,weight and power consumption of strapdown inertial navigation systems(SINS),a navigation computer featured with closecoupled masterslave dual processors is developed,which employs a digital signal processor(DSP) as its navigation algorithm processor and a microcontroller as its I/O interface processor.The two processors are connected with a high speed parallel interface and their softwares are based on a protocol of masterslave pipeline. So the navigation computer can work fluently and rapidly,and the requirements for some SINS on navigation computers' I/O , data processing capability,size,weight,power consumption,etc,are met. |
