| description | Techniques and mechanisms for transparently transitioning an interconnect fabric between a first frequency and a second frequency. In an embodiment, the fabric is coupled to an end point device via an asynchronous device. One or more nodes of the fabric operate in a first clock domain based on a clock signal, while the end point device operates in a different clock domain. Controller circuitry changes a frequency of the clock signal by stalling the clock signal throughout a first period of time which is greater than a duration of three cycles of a lower one of the first frequency or the second frequency. After the first period of time, cycling of the clock signal is provided at the second frequency. In another embodiment, the asynchronous device enables the frequency change without preventing communication with the end point device. |
