Working Principle

The processor contains a memory management unit (MMU) which determines the address space where each process or thread is allowed to access its data or instructions. The MMU ensures a secure environment as it ensures isolation between processes or threads on the processor. The MMU also enables the processor to efficiently manage the different types of resources on the device such as DRAM and SRAM.

The processor also contains a power management unit (PMU) which handles the power-saving mode. The PMU is responsible for managing the power consumed by different modules of the processor such as the CPU and GPU.

The processor also utilizes an interrupt controller which is responsible for the management of hardware interrupts. The interrupt controller is responsible for detecting and dispatching interrupts from the hardware to the software. The interrupt controller also contains several registers which can be used to configure and control the interrupt state of the system.

The processor also utilizes a timer control unit (TCU) to control and manage the system time. The TCU is responsible for setting and managing the system time. The TCU also contains several registers which can be used to configure and control the system time.

Lastly, the processor contains an on-chip debug module (ODM). The ODM is responsible for the debugging of the entire device. The ODM contains several registers which can be used to configure the ODM and access the contents of the CPU and GPU memories.
