    • A slot machine comprises a central processing unit (CPU) and a reel mechanism. The CPU operates the slot machine and randomly determines a game outcome in response to a wager. The reel mechanism includes a motor, a symbol-bearing reel, and a reel driver. The motor includes a rotatable shaft, and the reel is mounted to the shaft. The reel driver includes a local microcontroller distinct from and coupled to the CPU. The reel driver is coupled to the motor to cause the motor to rotate the reel. The CPU issues high-level commands to the reel driver related to rotation of the reel. The high-level commands may, for example, include a start spin command for starting rotation of the reel and a stop command for stopping the reel at a specified position. However, to free up the CPU for other tasks, the local microcontroller performs low-level reel driver operations related to the rotation of the reel. The low-level reel driver operations may, for example, include sampling a state of the reel in real time, performing calculations, and responding with control changes.
    • 老虎机包括中央处理单元(CPU)和卷轴机构。 CPU操作老虎机,并根据下注随机确定游戏结果。 卷轴机构包括马达,符号承载卷轴和卷轴驱动器。 电动机包括可旋转轴,并且卷轴安装到轴上。 卷轴驱动器包括与CPU不同且耦合到CPU的本地微控制器。 卷轴驱动器联接到马达以使马达旋转卷轴。 CPU向卷轴驱动器发出与卷轴转动相关的高级命令。 高级命令可以例如包括用于开始卷轴旋转的开始旋转命令和用于在指定位置停止卷轴的停止命令。 然而,为了释放CPU用于其他任务,本地微控制器执行与卷轴旋转相关的低级卷轴驱动器操作。 低级卷轴驱动器操作可以例如包括实时地对卷轴的状态进行采样,执行计算以及响应控制变化。
