Abstract: A system for preventing processor errors in accordance with one exemplary embodiment of the present disclosure has a processor core, a patch, and a controller. The patch configures the processor core to detect occurrences of an event indicative of an imminent error in the processor core. The controller is configured to adjust, in response to a detection of an occurrence of the event by the processor core, a clock signal or a power signal provided to the processor core such that the imminent error is prevented.

Abstract: A processor comprises a processor core and a controller. The processor core has an execution unit configured to execute instructions and to attempt to perform at least one operation in executing one of the instructions. The processor core is configured to detect a processor error associated with the at least one operation. The controller is configured to change an operating point of the processor core in response to a detection of the processor error such that the processor core operates at a new operating point, and the processor core is configured to retry the at least one operation while the processor core is operating at the new operating point.

Abstract: A processor comprises a chip, a temperature sensing device, a processor core, and a controller. The temperature sensing device, the processor core, and the controller are integrated on the chip. The controller is configured to set, based on the temperature sensing device, the processor core to a plurality of specified operating points to enable testing of the specified operating points. Each of the operating points is defined by a different temperature and frequency combination, and the processor core is configured to run a set of test codes at each of the operating points.

Abstract: A system and method for generating a graphical representation of fault data of a memory device under test is disclosed. A location-specific count of failing locations of the memory device is maintained as varying parameters are applied to the memory device. A symbol is assigned to each failing location based on its location-specific count. The symbols are plotted in an array representative of the memory device under test.
