摘　　要：以某型声探测设备软件设计为例,介绍一种以双片数字信号处理器(Digital Signal Process,DSP)(FT-C6713J400)、微控制单元(Micro Control Unit,MCU)和现场可编程逻辑门阵列(Field Programmable Gate Array,FPGA)为核心的全国产芯片信号采集和处理系统。详细描述FT-C6713J400的软件时序设计、软件状态转换设计、软件中断设计及其编程实现,并列出核心代码。结果表明,以国产芯片FT-C6713J400为核心的信号处理软件不仅能够满足声探测算法较大的计算量,而且通过处理时序的设计实现了双片DSP在工作时保持配合同步,满足探测系统的实时性要求。该软件还设计了数据库更新功能,通过上位机分包下发数据库信息,能够实现嵌入式软件接收和在线更新数据库功能。Taking the software design of a certain type of acoustic detection equipment as an example, this paper introduces a signal acquisition and processing system based on a national chip with dual Digital Signal Process(DSP)□Micro Control Unit(MCU) and Field Programmable Gate Array(FPGA) as the core. This paper describes in detail the software timing design, software state machine transformation design, software interrupt design and its programming implementation of FT-C6713J400, and lists the core code. The results shows that the processing software with domestic chip as the core can not only meet the large amount of calculation of acoustic detection algorithm, but also realize the synchronization of two DSPs during operation through the design of processing timing, so as to meet the real-time requirements of detection system. The software also designs the database update function, which can receive and update the database online through the subcontracting of the upper computer.
