Abstract
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.
