摘要
本文介绍了一种高速虚拟仪器采集平台的设计理论和实现方法,从硬件构成和软件设计两个方面详细介绍了系统的组成。该采集平台基于高速模数转换器ADC08D1500和高性能可编程逻辑器件VIRTEX-4 SX35,可以实现3Gsps的实时采样率和8位的采样精度;板载512M DDR2内存模组,可以实现高速信号的实时存储;硬件平台具有灵活的时钟和触发电路设计,可以满足不同用途的需要;软件开发上采用DLL+API的模式,方便不同用户的定制。
This paper introduced a design principles and implementation method of a general data acquisition platform of high speed virtual instrument. It described the hardware and software of the system. This platform is based on an ultra high speed ADC08D1500 and high performance FPGA-VIRTEX-4 SX35, and it realized 3Gsps real time sample rate and 8 bit sample resolutions; On-board DDR2 DRAM module can realize high speed data real time storage; the hardware platform contained flexible clock＆trigger circuit which can satisfy different purposes; DLL＋API mode are used in software development, convenient for different user＇ s customization.
