FIR转成Lattice结构[全零点系统转lattice） 根据要求的中心频点，及其相邻“梳齿”的峰值频率可选择。优点：结构简单，处理速度快。 -FIR into Lattice structure [the whole system turn against lattice] in accordance with the requirements of the center frequency, and its adjacent " comb" of the peak

在arm系统中，经常用到的小型MP3算法，该算法速度相当快，代码效率很高，而且提供了定点版本，对应用于arm系统是不二的选择-In the arm system, a small MP3 algorithm is often used, the speed of the algorithm is quite fast, code with high efficiency, but also provides a fixed-point version, the application in th
