A multi-channel large-capacity acquisition and storage system

摘要

In this paper, a multi-channel large-capacity acquisition and storage system is prototyped to meet the urgent need of multi-channel analog signals' acquisition and analysis. Composed of an acquisition board and storage board based on FPGA, the system could acquire 4 channel signals and store them in 512GB flash array. Gigabit Ethernet is used to connect the system and PC, which ensures high throughout between them. Ping-pong operation and pipeline technology are applied to cover the programming time of flash to improve the access speed. The system is portable, stable, and expansible, and could be used in various areas.
