基于FPGA的高速采样单元实现

摘要

A high-speed sampling unit hardware realization based on FPGA is proposed, including the circuit design of data acquisition ; the approach of high speed data transmission ; the design of operational processor system and bus control system, and the VHDL program framework. The signal types are iransformed by the sampler and then processed and stored with programmable gate arrays FPGA. Finally, the data of the sample unit is transmitted under the control of the whole system.%介绍了一种基于FPGA的高速采样单元硬件实现，包括数据采集器周边电路设计、高速数据传输方法和设计要点、运算处理单元设计、总线控制设计和VHDL程序编写框架。将信号进行样式转换，由采样器转换并通过可编程门阵列FPGA进行处理并存储，再由系统进行控制完成整个采样单元的数据传输。
