    摘要: A first input signal is received at a data input of first synchronizer, the first data input to be synchronized to a clock. A second input signal is received at a data input of second synchronizer, the second signal to be synchronized to the clock. Transitions are prevented from being received at a clock input of the first synchronizer and from being received at a the clock input of the second synchronizer in response to the first input signal having the same logic value as a first output signal at an output of the first synchronizer and the second input signal having the same logic value as a second output signal at an output of the second synchronizer.

    摘要: A data processing system may comprise an initiator device having an output whose timing is referenced by a clock input alone corresponding to a first delay along a signaling path. The exemplary data processing system further may further comprise a target device having an input whose timing is referenced by a clock input alone corresponding to a second delay along the signaling path and a system bus interconnected between the initiator device and the target device within the signaling path. The exemplary data processing system may further comprise a dynamic timing bridge coupled to the system bus within the signaling path, wherein responsive to a control signal representative of at least one system characteristic, the dynamic timing bridge performs one selected from the group consisting of (i) inserting a cyclic latency within the signaling path and (ii) not inserting the cyclic latency within the signaling path.

    摘要: A method of operating a bus interconnect coupled to bus masters and bus slaves is provided. The method includes receiving a request from a bus master to perform a bus transaction associated with a transaction ID with a bus slave of the plurality of bus slaves, the bus transaction being a first type of bus transaction. The method further includes performing the transaction if a resource allocation parameter allocated to the bus master meets a first threshold. The method further includes if the resource allocation parameter does not meet the first threshold, performing the data transaction only if the transaction meets a condition of a set of at least one condition, wherein a condition of the set of at least one condition includes that the transaction ID of the transaction is not a transaction ID of any outstanding bus transaction of the first type requested by the bus master.
