    摘要： An integrated circuit includes a plurality of processing stages each including processing logic, a non-delayed signal-capture element, a delayed signal-capture element and a comparator. The non-delayed signal-capture element captures an output from the processing logic at a non-delayed capture time. At a later delayed capture time, the delayed signal-capture element also captures a value from the processing logic. An error detection circuit and error correction circuit detect and correct random errors in the delayed value and supplies an error-checked delayed value to the comparator. The comparator 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： An integrated circuit includes a plurality of processing stages each including processing logic 2, a non-delayed latch 4, a delayed latch 8 and a comparator 6. The non-delayed latch 4 captures an output from the processing logic 2 at a non-delayed capture time. At a later delayed capture time, the delayed latch 8 also captures a value from the processing logic 2. The comparator 6 compares these values and if they are not equal this indicates that the non-delayed value was captured too soon and should be replaced by the 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 maimer that increases overall performance.

    摘要： An integrated circuit 2 has a specified range of runtime-variable operating parameters. Data processing circuits 4 within the integrated circuit 2 have associated error detection and error repair mechanisms 6. When operating within a narrow typical-case range of runtime-variable operating parameters the data processing circuits 4 operate correctly and substantially without error. When operating outside of this typical-case range but inside the specified range of permitted values for the run-time variable operating parameters, then the error detection and error repair circuit 6 operate to repair the errors which occur.

    摘要： An integrated circuit having a plurality of processing stages includes a low power mode controller operable to control the integrated circuit to switch between an operational mode and a standby mode. At least one of the processing stages has a non-delayed latch to capture a non-delayed value of an output signal from that processing stage and a delayed latch operable during the operational mode to capture a delayed value of the same signal. A difference between these two captured signals is indicative of the processing operation not being completed at the time the non-delayed signal was captured. The delayed latch is operable during the standby mode to retain the signal it captured whilst the non-delayed latch is powered down and loses its value. The delayed latch is formed to have a lower power consumption than the non-delayed latch.
