Microprocessors can have design errors that escape the test and validation process. The cost to rectify these errors after shipping the processors can be very expensive as it may require replacing the processors and stalling the shipment. In this paper, we discuss architecture support to allow patching the design errors in the processors that have already been shipped out. A contribution of this paper is our analysis showing that a majority of errors can be detected by monitoring a subset of… CONTINUE READING
