在现代控制系统中,控制规律是通过一组向量的运算来实现的。而针对数字滤波的特点而设计的数字信号处理器(DSP)采用改良的哈佛结构,适合于向量的运算。所以DSP进入控制领域是很自然的事。Analog Devices运动控制部主任Phil Davies说:DSP和微控制器的主要区别在于,DSP可以在一个时钟周期内完成乘加运算 In modern control systems, control laws are implemented through the operation of a set of vectors. The digital signal processor (DSP) designed for the characteristics of digital filtering uses a modified Harvard architecture and is suitable for vector operations. So it is very natural that DSP enters the control field. Phil Davies, director of motion control at Analog Devices, said: "The main difference between DSPs and microcontrollers is that the DSP can perform multiply and accumulate operations in one clock cycle
