APPARATUS AND METHOD FOR BOOTING AN APPLICATION PROCESSOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240320341 titled 'APPARATUS AND METHOD FOR BOOTING AN APPLICATION PROCESSOR
Simplified Explanation: The patent application describes a method and apparatus for booting a processor directly into a paged 64-bit execution environment. This involves initializing the processor using specific values and data structures to enable the execution environment.
- The processor includes a register to store values related to a secure boot process.
- It has multiple cores, with at least one core responsible for clearing registers and reading initialization messages.
- The initialization process involves checking if a specific mode is supported and using state values from a data structure to initialize the 64-bit execution environment.
Key Features and Innovation:
- Direct booting into a paged 64-bit execution environment.
- Secure boot process with specific values stored in registers.
- Use of data structures to enable the execution environment.
- Initialization based on supported modes and state values.
Potential Applications: This technology can be applied in secure boot processes for processors, ensuring a safe and efficient initialization into a 64-bit execution environment.
Problems Solved: This technology addresses the need for a secure and efficient boot process for processors, especially when transitioning into a 64-bit execution environment.
Benefits:
- Enhanced security during boot processes.
- Efficient initialization into a 64-bit execution environment.
- Clear and structured method for processor booting.
Commercial Applications: The technology can be utilized in various industries where secure boot processes and efficient processor initialization are crucial, such as in data centers, cloud computing, and high-performance computing systems.
Prior Art: Readers can explore prior research on secure boot processes for processors and methods for initializing 64-bit execution environments to understand the existing knowledge in this field.
