基于FPGA的新型虚拟逻辑分析仪的设计

摘要

提出了一种基于FPGA的虚拟逻辑分析仪的设计.该系统对采集到的模拟或数字信号进行存储、处理和逻辑分析.通过FPGA控制数据单次或连续采集、缓冲,通过PCI总线将缓冲区数据转移到硬盘管理卡,由硬盘管理卡将数据存入海量硬盘.%This paper presents a design of a virtual logic analyzer based on FPGA. The system of collection of analog or digital signals for storage, processing and logical analysis. Through the FPGA to control a single or continuous acquisition of data, buffer, buffer the data through the PCI bus will be transferred to the hard disk management card, a hard disk management card data into the massive hard drive.
