Abstract:
1. A method, in a data processing system, for dynamically burning-in cores of a multicore integrated circuit chip, comprising: applying an initial burn-in operation to a plurality of cores of the multicore integrated circuit chip based on an initial set of core burn-in parameters for the plurality of cores; measuring core operational characteristics of the plurality of cores; adjusting core burn-in parameters for at least one core of the plurality of cores based on the measured core operational characteristics to thereby generate a second set of core burn-in parameters; and applying a dynamic burn-in operation to the at least one core of the plurality of cores based on the second set of core burn-in parameters, wherein at least two cores of the multicore integrated circuit chip are burned-in using different burn-in voltages based on the dynamic burn-in operation.
