摘要
为了满足转子参数遥测时海量数据实时存储的需求,提出了一种基于FPGA和ATA硬盘的嵌入式高速数据存储系统设计方案。重点研究了ATAPI-6(AT attachment with packet interface-6)协议中ATA主机控制器的工作流程和Ultra DMA传输的关键时序,在此基础上设计了基于FPGA的ATA主机控制器。最后进行了数据存储试验,该控制器最高持续存储速度达24 MB/s,满足高速数据的实时存储需求。
In the parameters telemetry for rotating machinery,a real-time data storage device for memorizing the high-speed transmitted data is required.An embedded high-speed data storage system based on FPGA（field programmable gate array）/ATA hard disk is brought forward.The working-flow of ATA host controller is devised according to the ATAPI-6（AT attachment with packet interface-6） protocol.Ultra DMA transmission timing is analyzed,and the ATA host controller is built on FPGA.Data storage experiment was carried out,and the storing speed reached up to 24 MB/s,which satisfied the real-time storage requirement of mass data.
