基于FPGA的铁路语音记录系统的设计与实现

Design and Implementation of FPGA-based Railroad Voice Recording System

针对现有的铁路语音记录系统缓充池容量小、存储时间短的现状,采用FPGA器件构造双缓冲池,改进了传统语音存储在线缓冲技术.实验结果表明,本研究所设计的基于FPGA的铁路语音记录系统较以往类似的语音记录系统在存储容量上有很大提高,在线播放功能较传统的单缓冲池语音记录系统也有很大改善.

Considering that the existing railroad voice recording system has small buffer pool and short storage time,we use FPGA devices to construct double buffer pools and improve the online buffering technology of traditional voice storage. The experimental results show that the designed system in this paper has much greater storage capacity than the previous similar voice recording systems,and its online playing feature is also improved more greatly than that of the traditional voice recording systems with single buffer pool.
