摘要： An integrated circuit 2 includes logic circuitry 10 and sequential storage elements 8. Both the logic circuit 10 and sequential storage elements 8 can be subject to particle strikes giving rise to single event upset errors. These single event upset errors can be detected by detecting a transition in the stored value stored by the sequential storage elements 8 occurring outside of a valid transition period associated with that sequential storage element 8.

摘要： An integrated circuit is provided with domino logic including a speculative node and a checker node. Precharged circuitry precharges both the speculative node and the checker node. Logic circuitry provides a discharge path for the speculative node and the checker node in dependence upon input signal values. Evaluation control circuitry first couples the speculative node to the logic circuitry and then subsequently couples the checker node to the logic circuitry such that these can be discharged if the input signals to the logic circuitry have appropriate values. Error detection circuitry detects an error when the speculative node and the checker node are not one of both discharged or both undischarged.

摘要： An integrated circuit includes a plurality of processing stages each including processing logic 1014, a non-delayed signal-capture element 1016, a delayed signal-capture element 1018 and a comparator 1024. The non-delayed signal-capture element 1016 captures an output from the processing logic 1014 at a non-delayed capture time. At a later delayed capture time, the delayed signal-capture element 1018 also captures a value from the processing logic 1014. An error detection circuit 1026 and error correction circuit 1028 detect and correct random errors in the delayed value and supplies an error-checked delayed value to the comparator 1024. The comparator 1024 compares the error-checked delayed value and the non-delayed value and if they are not equal this indicates that the non-delayed value was captured too soon and should be replaced by the error-checked delayed value. The non-delayed value is passed to the subsequent processing stage immediately following its capture and accordingly error recovery mechanisms are used to suppress the erroneous processing which has occurred by the subsequent processing stages, such as gating the clock and allowing the correct signal values to propagate through the subsequent processing logic before restarting the clock. The operating parameters of the integrated circuit, such as the clock frequency, the operating voltage, the body biased voltage, temperature and the like are adjusted so as to maintain a finite non-zero error rate in a manner that increases overall performance.

摘要： A data processing apparatus and method are provided that use monitoring circuitry to control operating parameters of the data processing apparatus. The data processing apparatus has functional circuitry for performing data processing, the functional circuitry including error correction circuitry configured to detect errors in operation of the functional circuitry and to repair those errors in operation. Tuneable monitoring circuitry monitors a characteristic indicative of changes in signal propagation delay within the functional circuitry and produces a control signal dependent on the monitored characteristic. In a continuous tuning mode operation, the tuneable monitoring circuitry modifies the dependency between the monitored characteristic and the control signal in dependence upon certain characteristics of the errors detected by the error correction circuitry. An operating parameter controller is then arranged, in the continuous mode of operation, to control one or more performance controlling operating parameters of the data processing apparatus in dependence upon the control signal. This enables efficient and robust control of those operating parameters in response to changes in environmental conditions.

摘要： A data processing system 2 is used to perform processing operations to generate a result value. The processing circuitry which generates the result value has an error resistant portion 32 and an error prone portion 30. The probability of an error in operation of the error prone portion for a given set of operating parameters (clk, V) is greater than the probability of an error for that same set of operating parameters within the error resistant portion. Error detection circuitry 38 detects any errors arising in the error prone portion. Parameter control circuitry 40 responds to detected errors to adjust the set of operating parameters to maintain a non-zero error rate in the errors detected by the error detection circuitry. Errors within the one or more bits generated by the error prone portion are not corrected as the apparatus is tolerant to errors occurring within such bit values of the result value.
