    • A system having several clock domains must have domain clocks properly aligned before powering up from a low-power or power-down mode. The domain clocks can be quickly aligned to enable fast system start-up if the clocks are forced into a rough alignment before a fine alignment process begins. Initially, a phase offset between the domain clocks is determined using a sync pulse, which indicates a location of one of the domain clocks relative to the other domain clock. Next, the domain clocks are forced into a minimum phase offset configuration by phase stalling one of the domain clocks. The phase stalling includes adjusting the pulse width of one of the domain clocks to force the clock into a rough alignment with the other domain clock. Finally, the domain clocks are fine aligned, and the system is placed into a normal power mode.
    • 具有几个时钟域的系统在从低功耗或掉电模式上电之前必须具有正确对准的域时钟。 如果在精细对齐过程开始之前将时钟强制为粗略对齐,则域时钟可以快速对齐,以启用快速系统启动。 首先,使用同步脉冲来确定域时钟之间的相位偏移,该同步脉冲指示相对于另一个域时钟的域时钟之一的位置。 接下来,通过相位停止一个域时钟,将域时钟强制进入最小相位偏移配置。 相位失调包括调整其中一个域时钟的脉冲宽度,以强制时钟与其他域时钟粗略对齐。 最后,域时钟精细对齐,并将系统置于正常的电源模式。

    • An embodiment may comprise a counter to provide a count value, enable logic coupled with the counter, and circuitry coupled with the enable logic, the circuitry to be powered up or down if the counter value is outside of a resonance bandwidth for the circuitry to be powered up or down. An embodiment may comprise a method of initializing a counter while circuitry is placed in a standby mode, reading the counter, and powering up the circuitry if the counter does not indicate a resonance bandwidth. An embodiment may be a system comprising a device including a power delivery network to deliver power, a link coupled with the device, the link to electrically communicate with the device, and control circuitry coupled with the link, the control circuitry to limit the link from powering up or down at a resonant frequency of the power delivery network.
