The document presents a case study on the challenges and success of porting Android 4.4.4 to the PowerPC architecture for aerospace applications. Einfochips addressed various technical obstacles, including architecture differences and lack of documentation, to create an open, secure platform that benefits engine manufacturers and airlines by enhancing engine health management. This innovation allows for greater integration of Android in rugged aerospace environments, thereby improving operational efficiency and compliance.

1. Case Study : Porting Android 4.4.4
on PowerPC

2. Introduction
An Aircraft consists of many
complex systems, including
Flight controls, Landing gears,
Engine and Power trains,
Navigation controls, etc.
designed with stringent &
highest safety standards to
endure harsh environmental
conditions

3. Introduction
Engine plays very crucial role both in terms of cost
and safety of an aircraft……..!!!!!!
Also, health of the engine directly impacts:
• Efficiency of the aircraft
• Profitability of the airliners

4. Introduction
Thus, Engine Health Management (EHM) plays
crucial role for maximum functions:
• Manage Operation Costs
• Enhance Safety
• Preserve Value
• Reduce Downtime
• Operate at Peak Performance
• Receive Regular Reports
• Maintain Regulatory Compliance
• Corrective/Preventive Action Alerts

5. Executive Summary
Traditionally….
Engine Health management is being done by
engine manufacturers…!!!!!!!!

6. Executive Summary
Our customer, who is leading
engine manufacturer,,,
wanted to democratize it… !!!

7. Executive Summary
By providing access of engine data to
other stakeholders
Airlines
OEMs
Primes

8. Business Challenge
To have access to engine data
easily,, open source but secure
platform is necessary…!!!!

9. Business Challenge
Now, for open-
secure platform …
Android is the
obvious choice..!!!!!!!!

10. Business Challenge
PowerPC is most
widely used
architecture for
rugged application
like Aerospace

11. Business Challenge

12. eInfochips Challenge
Android is based on little
endian architecture
PowerPC is based on Big
endian architecture

13. eInfochips Challenges
No Documentation
No tool chain available for PowerPC
Requirement to modify scripts extensively
Bugs discovered
Mismatch in definition and declaration
Missing function for Big-endian operations

14. eInfochips Success
PowerPC (NXP T2081)
Android KitKat
4.4.4
eInfochips overcame all the
challenges and successfully
ported Android on PowerPC
