Abstract
Methods and apparatus to provide core sparing on multi-core platforms are described. In an embodiment, stored core state information of a target core (e.g., a core that has detected a fault condition (e.g., within its circuitry) or a request to offload operations from the target core (e.g., to enable run-time diagnostics without interfering with system software)) may be read by a spare core which is to operationally replace the target core. Other embodiments are also described.
