    • 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.
    • 集成电路包括多个处理级，每个处理级包括处理逻辑，非延迟信号捕获元件，延迟信号捕获元件和比较器。 非延迟信号捕获元件在非延迟捕获时间捕获来自处理逻辑的输出。 在稍后的延迟捕获时间，延迟信号捕获元件还捕获来自处理逻辑的值。 误差检测电路和误差校正电路检测并校正延迟值中的随机误差，并向比较器提供经错误检测的延迟值。 比较器比较错误检查的延迟值和非延迟值，如果它们不相等，则表示非延迟值被捕获太早，应由错误检查的延迟值替换。 非延迟值在其捕获之后立即传递到后续处理阶段，因此使用错误恢复机制来抑制后续处理阶段发生的错误处理，例如选通时钟并允许正确的信号值传播 在重新启动时钟之前通过后续的处理逻辑。 调整集成电路的工作参数，例如时钟频率，工作电压，主体偏置电压，温度等，以便以提高整体性能的方式保持有限的非零错误率。
