DSP定点算法在工控机上的模拟实现

Realization of Computer Simulation DSP Fixed-point Algorithm based on Industrial Computer

详细讨论了如何利用工业控制计算机对 DSP控制算法进行 C语言定点模拟 ,提出基于标么模型的定标方法 ,在利用标么模型编写 C语言的定点程序时 ,给出了具体的由于截尾或舍入产生的误差的处理方法以及溢出处理方法 ,最后讨论了为提高代码效率而对 DSP的

This paper presents how to simulate the C language fixed point for DSP control algorithm with industrial computer,and describes a method of Per Unit scale mode,and how to deal with errors and overflow occurred in truncation and round-off in programming with this method.In the end,the optimization of C code language fixed point for DSP for higher efficiency is discussed.
