本文探索了使单片可编程数字信号处理器(DSP)获得超群性能的结构特征。其中包括硬件乘法/累加器、并行存贮器结构,低超前循环(Low-Overhead Looping),寻址算术单元及流水线等具有特色的结构。本文以 AT&T、Motorola 及 Texas 等三个厂家的有关芯片,来说明结构与性能的关系。最后,还给出了对 DSP 的将来发展的某些预测。 This article explores the structural features that allow a monolithic programmable digital signal processor (DSP) to achieve superior performance. These include hardware multiply / accumulators, parallel memory structures, Low-Overhead Looping, addressable arithmetic units, and pipelined features. In this paper, AT & T, Motorola and Texas, the three manufacturers of the chip, to illustrate the relationship between structure and performance. Finally, some predictions of the future development of DSP are also given.
