Abstract:
A microprocessor includes an indicator and a plurality of processing cores. Each of the plurality of processing cores is configured to generate a default core ID and to sample the indicator. When the indicator indicates a first predetermined value, the default core ID generated by a default one of the plurality of processing cores designates the default processing core to be a bootstrap processor. When the indicator indicates a second predetermined value distinct from the first predetermined value, the plurality of processing cores are configured to generate alternate core IDs that are different from the default core IDs. One of the alternate core IDs designates an alternate processing core, other than the default processing core, to be the bootstrap processor.
