摘　　要：为了在海量数据采集系统中能够使用几百路传感器对模拟信号进行高速采集并将数据实时存储,设计了一种在FPGA内部实现硬盘控制的方法.通过PIO传输模式进行以扇区为单位的数据传输,将异步FIFO内的数据存入硬盘,平均写入速度达到12.56Mb/s,以状态机为核心,分析了使用Verilgo HDL语言实现硬盘寄存器读写和PIO数据传输的过程.在目标板上进行硬盘存储实验,通过SignalTapⅡ Logic Analyzer逻辑分析仪对硬盘控制器的功能进行验证,采集数据可达到0.8Mb/s的实时存储.Hundreds of sensors need to be used to collect the analog signals and store the data at real time in massive data acquisition system. A high speed hard disk storage equipment and its system based on FPGA were introduced. The PIO transmission form was used to transmit the data based on the sector from FIFO in the speed of 12.56 Mb/s. The read-write and PIO data transmission processes of hard disk register rising VerilogHDL language were analyzed through taking the status machine as the kernel. The hard disk storing experiments on the object board prove the feasibility of the storage by the SignalTap Ⅱ Logic Analyzer. The real-time storage rate for the collected data can reach 0.8 Mb/s.
