DEVICE, METHOD AND SYSTEM TO DETERMINE A MODE OF PROCESSOR OPERATION BASED ON PAGE TABLE METADATA - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240111539 titled 'DEVICE, METHOD AND SYSTEM TO DETERMINE A MODE OF PROCESSOR OPERATION BASED ON PAGE TABLE METADATA
Simplified Explanation
The abstract describes techniques and mechanisms for a processor to determine an operational mode based on metadata for a page table. The processor identifies an entry in the page table that indicates the location of an instruction based on a pointer to the next instruction. The metadata in the page table includes an identifier of an operational mode of the processor, which is used to transition the processor to the appropriate operational mode for executing the instruction.
- The processor detects a pointer to the next instruction in a sequence of instructions.
- The page table is identified based on the pointer, and it contains metadata indicating the operational mode of the processor.
- The processor transitions to the operational mode specified in the metadata in preparation for executing the instruction.
- The operational mode can be one of multiple modes corresponding to different instruction set architectures.
Potential Applications
This technology could be applied in various computing systems where processors need to switch between different operational modes based on the type of instruction being executed.
Problems Solved
This technology solves the problem of efficiently transitioning a processor to the appropriate operational mode for executing different types of instructions without manual intervention.
Benefits
- Improved performance and efficiency in executing instructions. - Simplified management of different instruction set architectures. - Enhanced flexibility in adapting to diverse computing requirements.
Potential Commercial Applications
- High-performance computing systems - Embedded systems - Mobile devices
Possible Prior Art
One possible prior art could be the use of microcode in processors to handle different instruction sets and operational modes.

The article does not discuss any limitations on the number of operational modes that can be efficiently supported by this technology.
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.
