System Architecture Overview

它还需要将CPU连接到其他组件（如GPU、加速器和显示单元）的系统组件。包括:

• The Generic Interrupt Controller (GIC) to handle interrupts from the system
• System Memory Management Units (SMMU) to provide security and partitioning in virtualized systems (also called Input Output Memory Management Units, IOMMU)
• Core Sight Debug and Trace to gain insight on what is happening in the device
• AMBA to provide standards for connecting system components together.

Methods of deployment of system components depends on the market the device is aimed at, for example Security, Mobile and Server systems.
