基于SOPC的高速数据采集系统设计

High-speed Data Acquisition System based on SOPC

设计了一种以FPGA为载体的SOPC的存储式低成本数据采集系统,在分析MAX1308模数转换器特性及转换时序的基础上,完成了ADC的连接及其外围电路设计。通过编程FPGA内部软核处理器microblaze和自定义数据采集IP核控制整个系统的时序状态,实现处理器和硬件控制器为核心的数据采集系统。实验结果表明,该设计能够实现低成本高速采集,多路同时采集速度达到16Mb/s,并使用闪速存储器FLASH实现高速存储。

Design the storage-type low-cost data acquisition system based on SOPC which is with the FPGA as the carrier.According to analyze the characteristics and conversion timing of MAX1308 ADC,the ADC circuit and its peripheral circuits was designed.By way of programming Microblaze soft core processor within the FPGA and customizing IP core,it controls the entire system timing state.As the core of Processor and hardware controllers can realize its data acquisition system.The experi-mental results show that the designed system can achieve low-cost high-speed acquisition.Multiple simultaneous acquisition speed is greater than 16MB / s,and using Flash ROM can achieve High-speed storage.
