20080244133 | Data processing apparatus and method for arbitrating access to a shared resource - A data processing apparatus and method are providing for arbitrating access to a shared resource. The data processing apparatus has a plurality of logic elements sharing access to the shared resource, and arbitration circuitry which is responsive to requests by one or more of the logic elements for access to the shared resource to perform a priority determination operation to select one of the requests as a winning request. The arbitration circuitry applies an arbitration policy to associate priorities with each logic element, the arbitration policy comprising multiple priority groups, each priority group having a different priority and containing at least one of the logic elements. Within each priority group, the arbitration circuitry applies a priority ordering operation to attribute relative priorities to the logic elements within that priority group. Responsive to a predetermined event, the arbitration circuitry re-applies the priority ordering operation within at least one priority group prior to a subsequent performance of the priority determination operation. Such an approach has been found to provide a particularly flexible mechanism for performing arbitration, allowing a wide variety of different arbitration schemes to be implemented using the same arbitration hardware. | 10-02-2008 |

The data processing apparatus has a plurality of logic elements, at least one of the logic elements being an initiator logic element for initiating transfers, and at least one of the logic elements being a recipient logic element for receiving transfers.

The communication path has at least one buffer circuit provided therein for propagating at least the payload data along the communication path. Further, a power control circuit is associated with the at least one buffer circuit, which is responsive to a control signal indicating whether the payload data on the communication path is valid. If the control signal indicates that the payload data is not valid, the power control circuit causes the associated at least one buffer circuit to enter a power saving state. The control signal is derived from at least one pre-existing signal associated with the transfer. This has been found to provide a particularly efficient and flexible technique for reducing leakage current in buffer circuits within the data processing apparatus. | 12-03-2009 |
20110066780 | Data processing apparatus and method for measuring a value of a predetermined property of transactions - A data processing apparatus and method for measuring a value of a predetermined property of transactions are provided. The data processing apparatus has initiator circuitry for initiating transactions, recipient circuitry for handling each transaction initiator by the initiator circuitry, and a communication path interconnecting the initiator circuitry and the recipient circuitry via which the transactions are propagated between the initiator circuitry and the recipient circuitry. Measurement circuitry is coupled to the communication path for measuring a value of a predetermined property of the transactions, such as the latency of those transactions. The measurement circuitry has active transaction count circuitry for maintaining an indication of the number of transactions in progress, and accumulator circuitry for maintaining an accumulator value which is increased dependent on the number of transactions in progress. Further, a value register is provided for maintaining an estimate of the value of the predetermined property. Each time a transaction in progress reaches a predetermined point, for example a transaction end point, the accumulator value is decreased dependent on the estimate currently stored in the value register, and further the estimate stored in the value register is updated dependent on the accumulator value. Via this feedback mechanism, the estimate stored in the value register quickly settles to the actual value of the predetermined property being measured, and accordingly such measurement circuitry provides a simple, low cost and flexible mechanism for measuring the value of a predetermined property of transactions. | 03-17-2011 |
20110145646 | Use of statistical representations of traffic flow in a data processing system - An apparatus and method are provided for performing verification tests for a design of a data processing system. The apparatus comprises a system under verification representing at least part of the design of the data processing system, and a transactor for connecting to an interface of the system under verification, and for generating signals for input to the system under verification via the interface during performance of the verification tests. Profile storage stores a profile providing a statistical representation of desired traffic flow at the interface, the statistical representation providing statistical information for a plurality of traffic attributes and also identifying at least one dependency between such traffic attributes. The transactor then references the profile in order to determine the signals to be generated, such that the signals generated take account of the specified dependencies identified in the profile. Such a mechanism enables the transactor to more realistically replicate the traffic flow that will be observed in the real system. Another aspect to the present invention provides a mechanism for generating such profiles. | 06-16-2011 |
