Design of High-Speed U Disk Recorder Based on FPGA+ARM

摘要:

为了满足对高速串行数据长时间实时显示存储的要求,提出了一种采用FPGA+ARM作为主控制器结合大容量Flash缓冲的设计方案;系统前端采用FPGA串并转换并控制Flash进行数据采集,后端采用ARM进行实时显示存储;该系统采集速率高,能够采集高达8.45 Mbps的输入数据,存储容量可扩;系统是针对两路输入速度高达460 800 bps的串行数据而设计的,经测试验证,数据存储可靠稳定,可广泛应用于飞行装置上。

Abstract:

In order to meet the requirements of high-speed serial data of long time display and storage, this paper proposes a design of host processor using FPGA+S5PV210 which combined with large-capacity Flash buffer. The front-end system using FPGA SERDES for data acquisition, which transforms and controls Flash, the backend using ARM for real-time display storage. The sampling rate of the system is high, the rate of its data inputting can up to 8.45 Mbps,the Storage capacity of it can be expanded. The design of the recorder is based on serial data which two-way data input speed is 460800bps,the data storage of the recorder is stable and reliable after testing and validation, which can be widely used in flight device. 
