    • An apparatus for controlling switching transients including a bus interface unit and a waveform shaper coupled to the bus interface unit and a peripheral device. The bus interface unit generates a number of control signals defining the beginning and end of an operation, where each control signal includes a transition from a first value to a second value over a period of time. The bus interface unit selects a critical control signal defined as the last control signal to start the operation and/or the first control signal to end the operation. The waveform shaper receives the selected control signal and modifies the control signal by increasing the period of time of the transition. The modified control signal is received by the peripheral device and a switching transient in the peripheral device is controlled.
    • 一种用于控制切换瞬变的装置,包括总线接口单元和耦合到总线接口单元和外围设备的波形整形器。 总线接口单元产生定义操作的开始和结束的多个控制信号,其中每个控制信号包括在一段时间内从第一值到第二值的转变。 总线接口单元选择定义为最后一个控制信号的关键控制信号以开始操作和/或第一控制信号以结束操作。 波形整形器接收所选择的控制信号,并通过增加转换时间来修改控制信号。 修改的控制信号由外围设备接收,并且外围设备中的切换瞬态被控制。
