Original Abstract Submitted

Techniques and mechanisms for a processor to determine an operational mode based on metadata for a page table. In an embodiment, an instruction fetch unit of the processor detects a pointer to a next instruction, in a sequence of instructions, which is to be prepared for execution with a core of the processor. Based on the pointer, a page table is identified as including an entry which indicates a location of the instruction. The page table includes, or otherwise corresponds to, metadata which comprises an identifier of an operational mode of the processor. Based on the metadata, the processor is transitioned to the operational mode in preparation for an execution of the instruction. In another embodiment, the operational mode is one of multiple operational modes which each correspond to a different instruction set architecture.
