摘要
从导航计算机实时性和时间可确定性的要求出发,结合niosⅡ的高度灵活性和可定制性的特点,设计了完全可控式双NiosⅡ处理器,实现了IEEE-754标准单浮点精度的cordic算法,并添加了硬件浮点运算的用户指令。最终的NiosⅡ系统非常适合捷联导航解算,是低成本、高性能的捷联式导航计算机的最佳选择。
The article bine with nios Ⅱ＇s high float cordic algorithm base tions. Make the final nios is base on the requirements of real-time and time certainty about strapdown navigation computer, com- flexibility and customizable, designed completely controlled double nios Ⅱ processors, realize the single- on IEEE-754 standard, and add the hardware floating-point calculations to user＇s customizable instruc- Ⅱ system extremely suits to strapdown navigation solutions, is the best choice for low cost, high performance of strapdown navigation computer.
