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 ;最后分析说明了此结构的优越性 When designing a real-time signal processing system, the proper processor architecture must be chosen based on the characteristics of the task. In meeting the performance indicators, but also consider the size, power consumption, maintainability and other factors. A brief description of the commonly used signal processing system type and processor structure is introduced. The architecture of DSP + ASIC processor which is gradually being widely used is introduced. Based on this, a linear array structure of real-time signal processing is presented. The structure of the concrete realization of the processor; the final analysis shows the superiority of this structure
