    摘要: An embodiment of the present invention is a technique to control clock distribution to a circuit. A scheduler schedules a sequence of a clock distribution of clock signals to a plurality of clock distribution domains (CKDOMs) in the circuit according to a state status of the circuit. A controller controls enabling the clock distribution to the CKDOMs according to the scheduled sequence.

    摘要: A system and method for processing signals determines rise and fall times of a driving signal, compares the rise and fall times to desired values, and independently controls the rise and fall times to equal the desired values. The rise and fall times may be controlled by generating one or more first correction bits based on a difference between the rise time and a corresponding one of the desired values, generating one or more second correction bits based on a difference between the fall time and a corresponding one of the desired values, and then separately applying the bits to independently control the rise and fall times of the driving signal. The driving signal may be an I/O signal or another type of signal.

    摘要: A technique includes locking a locked loop circuit onto a reference clock signal. The locking includes locking the lock loop circuit onto the reference clock signal in response to a first feedback signal provided by a first feedback path and locking the locked loop circuit onto the reference clock signal in response to a second feedback signal that is provided by a second feedback path.
