Security Isolation Apparatus and Method - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18344404 Titled 'Security Isolation Apparatus and Method'
Simplified Explanation
This abstract describes a system that consists of two subsystems within the same chip. The first subsystem has a higher security level compared to the second subsystem. The first subsystem includes an interrupt controller, which is responsible for managing interrupts from a peripheral device in the second subsystem. The purpose of this system is to provide isolation between subsystems of different security levels within the chip.
Original Abstract Submitted
A system includes a first subsystem and a second subsystem that are used in a same chip. A security level of a first physical resource included in the first subsystem is higher than a security level of a second physical resource included in the second subsystem. The first subsystem includes an interrupt controller, and the interrupt controller is configured to manage an interrupt of a peripheral of the second subsystem. Embodiments of this application are for isolation between subsystems of different security levels in a chip.
