    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: An adaptive hysteresis receiver processes a high speed digital signal. A differential receiver circuit compares the high speed digital signal to a reference voltage to generate an output signal. 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: 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.
