摘要
本文阐述了一种新颖的基于SOPC技术低温目标微弱信号采集器的开发设计,该方案将系统的多个功能模块集成在一款Altera公司推出的低成本、高密度、具有嵌入式NIOS软核CPU的Cyclone系列的现场可编程阵列(FPGA)上,大大提高了系统设计的灵活性、信号采集的可靠性和读取数据的速率。详细论述了基于NIOS信号采集器的软硬件实现,并重点描述了Avalon从外设的定制。
This paper describes an original design project of low temperature target weak signal acquisition device based on 5OPC technology. This design integrates multiple function module on a low cost and high density FPGA, belongs to Cyclone family, which is developed with embedded NiosII CPU by Altera corporation. It improves the flexibility of design, reliability of signal acquisition and speed rate of fetching data. The realization of signal acquisition device based on SOPC technology hardware and software is presented, and particularly discusses how to customize Avalon peripheral.
