摘要
In an embodiment, an integrated circuit may include one or more processors. Each processor may include multiple processor cores, and each core has a different design/implementation and performance level. For example, a core may be implemented for high performance, and another core may be implemented at a lower maximum performance, but may be optimized for efficiency. Additionally, in some embodiments, some features of the instruction set architecture implemented by the processor may be implemented in only one of the cores that make up the processor. If such a feature is invoked by a code sequence while a different core is active, the processor may swap cores to the core the implements the feature. Alternatively, an exception may be taken and an exception handler may be executed to identify the feature and activate the corresponding core.
