【摘要】 介绍了以FPGA为控制核心的核信号采集主控系统的设计。FPGA内实现的功能包括与计算机的通信,对ADC采样的控制,对采样信号的数字甄别、存储等。可在线对阈值及ADC的寄存器进行设置。整个控制系统包括存储器(FIFO)在一片FPGA内实现,系统硬件结构简单,能有效地提升核分析仪器的性能并有利于其小型化。更多还原

【Abstract】 Design of main control system for nuclear signal acquisition based on FPGA was introduced. The functions are all implemented in the FPGA including communicating with the computer,controlling sampling of ADC,threshold discrimination and storage of digital nuclear signal,etc. Threshold and the ADC registers can be set online. The whole control system including a memory( FIFO) is implemented in a FPGA. The hardware of the system is simple and the power consumption is low. The performance of the instrument is improved effectively and the size is reduced also.更多还原
