    摘要: A computer bus that enables bus mastering agents to send/receive a burst of data to/from a slave agent without determining in advance the number of data words to be transferred, or even the maximum number of data words that could be transferred. Either the master, the slave, or the bus arbiter can terminate the burst at any time with minimum overhead. Furthermore, either the master or the slave can throttle the speed of the data transfer by adding wait states. Distributed address decode is performed by each agent coupled to the bus. Each agent must claim a transaction directed toward it by the master. If no agent claims the transaction within a predetermined number of clock periods, a subtractive decode device may claim the transaction by default. The bus also includes a bus lock wherein each bus slave agent may be able to enter a locked state, and once in the locked state, reject all accesses except those initiated by the master agent that locked it. Signal line LOCK# is owned by only one master agent at a time. Although the LOCK# signal must be obtained by acquiring the bus while LOCK# is high, ownership of the line is maintained as long as LOCK# is held low. Therefore, a master agent can own the lock while another master uses the bus.

    摘要: The disclosure describes a multi-stage phase comparator and a phase-locked loop incorporating such a comparator. The comparator measures a phase difference between a reference signal and an output signal using a periodic clock. The comparator is a two stage comparator comprising a fine and coarse comparator. The coarse comparator measures the number of full clock periods between a transition of the reference signal and the output signal. The fine comparator comprises a delay line generator that generates a plurality of delayed clocks. The delayed clocks are used to over sample the reference signal to determine a fine phase difference representing a remaining fraction of the clock period, between transitions of the reference and output signals. A phase locked loop using the multi-stage comparator allows for more accurate phase locking.
