3**CMSIS-Zone** is an open source utility that helps to manage software configurations for partitions that have different access permissions to system resources in devices with Arm Cortex-M processors. It implements the infrastructure that is required for:
4
5 - Split of a multi-processor system for single processor views
6 - TrustZone setup (SAU, Interrupt assignment to Secure/Non-Secure)
7 - Setup of Memory Protection Unit (MPU)
8 - Setup of device specific Memory Protection Controller (MPC)
9 - Setup of device specific Peripheral Protection Controller (PPC)

20## Key Features and Benefits
21
22 - CMSIS-Zone reduces the complexity of configuring access permissions in embedded software.
23 - Allows to setup of access permissions to memory and peripherals in secure/non-secure modes, and privilege execution levels.
24 - Provides graphical (GUI) and command line (CLI) interfaces.
25 - Generates the code for the setup of protection hardware such as SAU, MPC, PPC, MPU.
26 - Generates the linker scripts for the defined partitions.
27 - Includes multiple examples for real hardware.
