论文摘要
原子，分子和光学（AMO）物理学的实验需要精确，准确地控制数字，模拟和射频（RF）信号。我们提出了一个基于字段可编程门阵列（FPGA）核心的控制硬件，该硬件通过简单的接口总线驱动各种模块。该系统支持10 MHz的工作频率，内存深度为8 m（2 $^{23} $）指令，均易于扩展。连续的实验序列可以没有死时间堆叠，并在任何指示下与外部事件同步。可以将两个或多个单元级联并同步到一个公共时钟，该功能可用于以模块化方式操作大型实验设置。
Experiments in Atomic, Molecular, and Optical (AMO) physics require precise and accurate control of digital, analog, and radio frequency (RF) signals. We present a control hardware based on a field programmable gate array (FPGA) core which drives various modules via a simple interface bus. The system supports an operating frequency of 10 MHz and a memory depth of 8 M (2$^{23}$) instructions, both easily scalable. Successive experimental sequences can be stacked with no dead time and synchronized with external events at any instructions. Two or more units can be cascaded and synchronized to a common clock, a feature useful to operate large experimental setups in a modular way.
