-Introducing Project ACRN
-########################
-
-The open source project ACRN, defines a device hypervisor reference
-stack and an architecture for running multiple software subsystems,
-managed securely, on a consolidated system by means of a virtual machine
-manager. It also defines a reference framework implementation for
-virtual device emulation, called the “ACRN Device Model”.
-
-The ACRN Hypervisor is a Type 1 reference hypervisor stack, running
-directly on the bare-metal hardware, and is suitable for a variety of
-IoT and embedded device solutions. The ACRN hypervisor addresses the gap
-that currently exists between datacenter hypervisors, and hard
-partitioning hypervisors. The ACRN hypervisor architecture partitions
-the system into different functional domains, with carefully selected
-guest OS sharing optimiztionsfor IoT and embedded devices.
-
-Automotive use case scenario
-****************************
-
-A good use case example for the ACRN Hypervisor is in an automotive
-scenario.  The ACRN hypervisor can be used for building a Software
-Defined Cockpit (SDC) or an In-Vehicle Experience (IVE) solution.  As a
-reference implementation, Project ACRN provides the basis for embedded
-hypervisor vendors to build solutions with a reference I/O mediation
-solution.
-
-For example, an automotive SDC system consists of the Instrument Cluster
-(IC) system, the In-Vehicle Infotainment (IVI) system, and one or more
-Rear Seat Entertainment (RSE) systems.  Each system can run on the same
-hardware as isolated Virtual Machines (VM), for overall system safety
-considerations.
-
-An **Instrument Cluster (IC)** system is used to show the driver operational
-information about the vehicle, such as:
-
-* the speed, the fuel level, trip mile and other driving information
-  of the car;
-* projecting heads-up images on the windshield, with alerts for low
-  fuel or tire pressure;
-* showing rear-view camera, and surround-view for parking assistance.
-
-An **In-Vehicle Infotainment (IVI)** system's capabilities can include:
-
-* navigation systems, radios, and other entertainment systems;
-* connection to mobile devices for phone calls, music, and
-  applications via voice recognition;
-* control interaction by gesture recognition or touch.
-
-A **Rear Seat Entertainment (RSE)** system could run:
-
-* entertainment system;
-* virtual office;
-* connection to the front-seat IVI system and mobile devices (cloud
-  connectivity).
-* connection to mobile devices for phone calls, music, and
-  applications via voice recognition;
-* control interaction by gesture recognition or touch
-
-The ACRN hypervisor supports both Linux* VM and Android* VM as a User
-OS, with the User OS managed by the ACRN hypervisor. Developers and OEMs
-can use this reference stack to run their own VMs, together with the IC,
-IVI, and RSE VMs. The Service OS runs as VM0, (also known as Dom0 in
-other hypervisors), and the User OS runs as VM1, (also known as DomU).
