摘　　要：设计实时信号处理系统时 ,必须根据任务的特点选择适当的处理机结构。在满足性能指标的同时 ,还要考虑体积、功耗、可维护性等因素。简要叙述了常用的信号处理系统类型与处理机结构 ;介绍了正逐步得到广泛应用的DSP +ASIC处理机结构 ;在此基础上提出了一种实时信号处理的线性流水阵列结构 ;举例说明了该结构处理机的具体实现 ;When designing real-time systems, the processing architecture should be chosen according to the characterisitcs of the task. Those constraints considered include performance, dimension, power and system maintenance. This paper briefly describes the general types and architectures of signal processing systems first, then introduces the up-to-date DSP+FPGA architecture. We also present a linear pipeline array model for real-time signal processing with an example illustrating its implementation. At last we discuss the advantage of this architecture.
