| Abstract: | 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. |
