A register circuit latches the output signal, according to a clock signal, to produce a control signal. A reference voltage generator generates the reference voltage, from a plurality of voltages defining a deep hysteresis level and a shallow hysteresis level, in response to the output signal and the control signal.

摘要： An apparatus and method for increasing the performance of a common-clock data bus is provided by borrowing time from the common-clock domain timing. The time may be borrowed by dynamically delaying the common-clock before providing it to a receiving path. In a system comprising a plurality of logic devices electrically coupled to a data bus, time may be borrowed from the internal common-clock timing domain of one of the plurality of logic devices when receiving data through the data bus from an external logic device. To prevent race conditions, a logic device of the plurality of logic devices may be configured to switch off the time borrowing when receiving data from an internal driving path. To avoid glitches, the logic device may be configured to switch the time borrowing feature on and off only at select time intervals.

摘要： A method and system for sampling on the fly one or more integrated circuit nodes coupled to one or more bus domain clocks of an integrated circuit using minimal clock cycle delay synchronization. Sample on the fly circuitry, set-reset circuitry and metastable rejection circuitry are used to provide a sufficient pulse width for sampling on the fly the one or more nodes when the one or more bus domain clocks require asynchronous operation. The sample on the fly circuitry is also operable to synchronously sample on the fly the one or more nodes.

摘要： Systems and methods for synchronizing an input signal with a substantial mitigation of race conditions and a substantial increase in resolving time are provided. One embodiment includes a system comprising a first latching device configured to latch a first output signal from the input signal and a delay element configured to receive the first output signal and output a delay signal that is a delayed version of the first output signal. The system also includes a pass-gate element configured to receive the first output signal and to output a second output signal in response to a logic state of the delay signal. The second output signal has a delayed input edge without a delayed resolving edge. The system can be configured to force the first output signal to a stable logic state in response to the first output signal having a metastable state.
