A High-speed Data Acquisition and Storage System Based on FPGA

Abstract

The invention discloses an FPGA-based high-speed data acquisition and storage system. The system comprises an FPGA core board, a data acquisition module, an MPU module, a gigabit Ethernet module, a display module, an input-output module and a storage module. The storage module is connected with a core device FPGA through DDR3; and interfaces of a display, a mouse, a keyboard, a gigabit network and the like are connected with a PCI-E Switch through the MPU module to realize data interaction with the FPGA. 2 MINISAS interface modules are directly connected with the FPGA to perform data interaction. The functions of data importing, data exporting, data analysis, data maintenance and the like can be realized through a software system of the system, and simple data real-time analysis can be realized. The system is high in data transmission rate, large in storage capacity and capable of performing field capacity expansion and bad block processing; the system has numerous interfaces, thereby having relatively good user experience; and the system is good in interactivity among module units and supports remote Ethernet control.

Description

technical field [0001] The invention relates to a high-speed data acquisition and storage system, in particular to an FPGA-based high-speed data acquisition and storage system. Background technique [0002] With the increasing popularity of electronic products, the rapid development of data acquisition technology and data storage technology has been driven. Especially in satellite navigation, electronics, radar and other technical fields, data acquisition and storage systems are playing a more and more important role. Moreover, the technical requirements for data acquisition and storage systems are also increasing: high data sampling rate, high data transmission rate, massive storage capacity, low power consumption and low cost. Traditional data acquisition and storage systems are difficult to meet such requirements. [0003] The FPGA (Field Programmable Gate Array, Field Programmable Gate Array) technology developed in recent years provides good technical support for a ne...
