1 Comprehensive Development and Debug Coverage for Linux and Android on the MIPS Architecture Presented by MIPS Technologies Powering a Connected World October 2010

2 Today s presenters: Rick Leatherman VP Development Tools MIPS Technologies Hieu Tran President & Founder of Viosoft Corporation Art Lee VP of Business Development, Viosoft Corp. MIPS Technologies Powering a Connected World

3 Agenda Android and its Migration to Non-mobile Applications Android and How It Compares to Traditional Linux Systems The Challenges of Debugging Android The Limitations of Traditional Debug Tools Viosoft Arriba Debugger Overview Brief Debug Demonstrations Android System Event Analyzer Summary Q & A 3

4 Overview of Google Android Software Platform 4

5 Taking Android beyond Mobile Handsets 5

6 Android on Non-Mobile Platforms HANDSET (99% COMPLETE) Assuming HW and Linux SW is EXACTLY the same Otherwise only 80% or less MID (70%) Embedded Device (???) STB (50%) 6

7 Android Enables Embedded Devices to Access the Cloud Connected Content Devices to experience connected content NOW 7

8 Repurposing Android Requires Tools that can Debug the Full Stack MIPS licensees, partners, and the community will contribute much of the longer-term effort 8

9 Android versus Traditional Linux Systems Traditional Linux Platforms Single language (some assembly, mostly C) Single/few processes Applications mostly execute in User Space One process per application Android Multiple languages (assembly, C/C++, Java, JavaScript, ActionScript) Multiple processes, with program logic straddling process barriers Applications partitioned between User and Kernel Space Multiple processes per application Android Software Development Android is a Juggling Act! 9

10 Why is Android Development so Difficult? (1) Android applications cross language barrier Java C/C++ Javascript & Actionscript (2) Android applications cross process barrier Client/Server JNI CORBA/IDL (3) Android applications cross protection barrier To and From User / Kernel Space

11 MIPS Strategic Alliance With Viosoft Corporation MIPS has partnered with Viosoft to offer the Arriba embedded Linux/Android debugger as part of the MIPS tools portfolio The Arriba debugger offer a very unique and powerful set of debug features Recently awarded a Best in Show Award by VDC for Android Development Tools We will showcase the Arriba debugger during today s Webinar 11
