我们知道数字计算催生了中央处理器,即CPU,于是开启了个人计算机的时代。随着数字化和网络化的推进,DSP作为一种新型的特殊处理器,从数字计算中脱颖而出,引领了数字信息产品的时代。可编程DSP的核心就是采用数字信号处理最基本的乘加结构,于是一条指令就可以完成数字滤波器的基础运算。同时DSP核心采用特别的内部存储寻址结构,以及灵活的辅助寄存器结构,从而以更高的效率实现实时信号处理。
We know that digital computing gave birth to the central processor, the CPU, which opened the era of personal computers. With the digitization and networking advances, DSP as a new type of special processor, stand out from the digital computing, leading the era of digital information products. The core of programmable DSP is to use digital signal processing of the most basic multiply-add structure, so an instruction can complete the basic calculations of digital filters. At the same time DSP core uses a special internal memory addressing structure, and a flexible secondary register structure, so as to achieve higher efficiency real-time signal processing.
