ACRN high-level design overview
|
|
###############################
|
|
|
|
ACRN is an open source reference hypervisor (HV) running on top of Intel
|
|
Apollo Lake platforms for Software Defined Cockpit (SDC) or In-Vehicle
|
|
Experience (IVE) solutions. ACRN provides embedded hypervisor vendors
|
|
with a reference I/O mediation solution with a permissive license and
|
|
provides auto makers a reference software stack for in-vehicle use.
|

|
|
ACRN Supported Use Cases
|
|
************************
|
|
|
|
Software Defined Cockpit
|
|
========================
|
|
|
|
The SDC system consists of multiple systems: the instrument cluster (IC)
|
|
system, the In-vehicle Infotainment (IVI) system, and one or more rear
|
|
seat entertainment (RSE) systems. Each system is run as a VM for better
|
|
isolation.
|
|
|
|
The Instrument Control (IC) system manages graphics display of
|
|
|
|
- driving speed, engine RPM, temperature, fuel level, odometer, trip mile, etc.
|
|
- alerts of low fuel or tire pressure
|
|
- rear-view camera(RVC) and surround-camera view for driving assistance.
|
|
|
|
In-Vehicle Infotainment
|
|
=======================
|
|
|
|
A typical In-Vehicle Infotainment (IVI) system would support:
|
|
|
|
- Navigation systems;
|
|
- Radios, audio and video playback;
|
|
- Mobile devices connection for calls, music and applications via voice
|
|
recognition and/or gesture Recognition / Touch.
|
|
- Rear-seat RSE services of entertainment system;
|
|
- virtual office;
|
|
- Connection to IVI front system and mobile devices (cloud
|
|
connectivity).
|
|
|
|
ACRN supports guest OSes of Clear Linux and Android. OEMs can use the ACRN
|
|
hypervisor and Linux or Android guest OS reference code to implement their own
|
|
VMs for a customized IC/IVI/RSE.
|
|
|
|
