近年来,日本和欧美各国广泛地开展了高速数字信号处理用的特殊微处理机的研制与应用的研究。这种用于实时信号处理的微处理机是以高集成化技术为基础,将高速乘法器、数据存储器、程序存储器集成在一块芯片上,此外,在微程序控制或内部总线等体系结构方面作些改进,这样,就能大幅地提高数字信号处理的吞吐量。图1示出了信号处理器(SP)的使用形式。使用形式虽有多种多样,诸如多芯片使用形式和作为通用微机的子处理机使用形式等等,但其基本形式仍是:对经A/D变换器交换的数字数值系列,作适当的信号处理
In recent years, Japan and countries in Europe and the United States have carried out extensive research on the development and application of special microprocessors for high-speed digital signal processing. The microprocessor for real-time signal processing is based on highly integrated technology, high-speed multiplier, data memory, program memory integrated in a chip, in addition, micro-program control or internal bus architecture Some improvements, in this way, can significantly improve the throughput of digital signal processing. Figure 1 shows the use of Signal Processors (SPs). Although there are various forms of use, such as the form of multi-chip use and the use of sub-processors as a general purpose microcomputer, etc., the basic form of the digital value series exchanged by the A / D converter is as follows deal with
