新近涌现的各种数字信号处t理器（ＤＳＰ）的规格尺寸繁多，外形各式各样，令人难以胜数，其设计目标也是为了满足各种对性能要求高低不同的应用。这些需求既包括附加在现有的处理器上、用于提供ＤＳＰ功能的简易编码器，也包括可以驱动整个第三代蜂窝式电话的高性能器件。早期
The recent emergence of a variety of digital signal processor (DSP) size specifications, a variety of shapes, it is difficult to win, the design goal is to meet a variety of performance requirements of different applications. These requirements include both simple encoders for adding DSP capabilities to existing processors and high-performance devices that power the entire third generation of cellular phones. Early
