Description: The Privileged Mode in ARM architecture is an operating state that allows full access to all system resources and instructions. This mode is fundamental for hardware management and the execution of critical tasks within an operating system. In this state, the processor can execute instructions that are not available in lower privilege modes, such as User Mode. This includes the ability to access special registers, control interrupts, and manage memory more effectively. Privileged Mode is essential for ensuring system security and stability, as it allows the operating system to control access to resources and protect the integrity of applications running in User Mode. The ARM architecture, widely used in mobile devices and embedded systems, implements this mode as part of its design to optimize performance and security. The transition between modes is performed through specific instructions, allowing the operating system to switch from User Mode to Privileged Mode when necessary, thus ensuring that critical operations are carried out in a controlled and secure manner.
