摘　　要：以某探测系统软件设计为例,介绍了一种以双片ADSP-TS201S和FPGA为核心的信号采集和处理系统。详细描述了TS201S的软件时序设计、自动程控增益设计,以及系统中断的设计和编程实现,并列出了核心代码;介绍了双片TS201S的程序加载方式和软件编程优化方法。结果表明,以FPGA和双片ADSP-TS201S为核心的信号采集和处理系统不仅能够满足探测算法中计算量庞大、处理复杂的要求,而且能够自动进行增益控制,通过对时序的设计实现了双片ADSP-TS201S在工作时保持准确的同步,满足探测系统的实时性要求。According to the detection system software design, a signal sampling and processing system is presented in this paper, which use the dual -chip ADSP- TS201S and FPGA as its core. The TS201S software sequential design, automatic programmable gain design, and system interrupts design with core code are described. In addition, the dual -chip TS201S boot mode and software programming optimization method are introduced. The results show that the requirements of the huge computation and complex processing in this detection system are met and control of the gain automatically is achieved by using the signal sampling and processing system based on dual -chip ADSP- TS201S and FPGA. The sequential design can make the dual -chip ADSP- TS201S keep accurate synchronization, and meet the real- time requirement.
