Motivation Facilitating a dynamic and agile yet predictable portfolio

Facilitate HW migration (towards innovative HW)

Product innovation is intimately tied to change, and often the needfor change appears midstream in a project.

The ability to make changes during development without being toodisruptive can be valuable

a s y cus omers: cou e ac eve y a us ng pro ucrequirements during development in response to customerfeedback.

TTM could be measured from the last change in requirements untilthe product is delivered.

Scope (HW/SW integration) Lead Product andsubsequent products

Why do products flop? Fail to deliver expected performance

Too late Competitors got the upper hand

Not attractive to consumers even if fulfillingrequirements

Even if it sales well doesnt pay for itself Development

cost was too high

Wouldnt it be better if

Bring to the start what causes problems in the end

UI/Apps dev starts while finalizing requirements Simulator Kernel/basic drivers (FlashMem/Keyboard/LCD/USB/SD Card)

up and running ASAP Minimal dev effort, off the shelfcomponents available

Fast vertical bring up tried and tested (but representative)UI/App frameworks on new or phone form factor

Transition UI dev from Simulator to HW

Horizontal Bring-up Sequentially hook peripherals (minimum

integration effort) Integration Tests driven from UI (Smoke, Stability,

Interoperability)

Minimal effort to spin-off HW variants

Kernel is open now

Development kit available low adoption barrier

Kernel EPL is available through PDK as well

Will Provide Starting Point and Off-the-shelfcomponents

What is SHAI? Symbian Hardware Abstraction Interface

A standard for HW abstraction for Symbian OS based devices

New definition of Symbian/S60 Adaptation

Based on S60 Chipset API's, expands also to area of peripheralcomponent abstraction

Common HW adaptation standard across Symbian Foundationmember companies

Future evolution managed through Symbian Foundation in

collaborative OSS mode

Most of the initial adaptation provided by Nokia through packageowners

Why SHAI? We need to secure our future access to most compelling HW

technologies

Industry commitment to Symbian Foundation will increase availableHW options for Symbian -powered devices

Quicker productisation of new HW offering and more options for HWcomponent sourcing

Lower barrier for extending the SHAI compliancy to wider range ofHW modules

Technical soundness and productivity increase (for OEMs and HWvendors)

Active and healthy ecosystem -> will ensure overall HWcompetitivness of Symbian powered devices

Drivers and benefits of SHAI

Lower costs, better productivity Less effort and shorter TTM in porting SW to new HW

Remove unneccessary duplicate investments in non-differentiating areas in Symbian Foundation Ecosystem

Enable HW vendors to supply one standard solution to allcustomers

Clear worksplit HW vendors to supply Adaptation SW specific to their HW

Industry best HW Abstraction Interface and Architecture for Symbian

The SHAI story so far Nokia contributed major parts of S60 Chipset APIs to Symbian

Foundation (June -09)

Established SHAI WG, chaired by Daniel Rubio

Other members (as of today) from: Nokia, Samsung,Broadcomm, Fujitsu, STE, NTT-DoCoMo, TI, SEMC

WG Members are currently reviewing and providing comments onthe API proposals

Community feedback is very positive so far High anticipation for the initiative

Considered as a significant development proposal to SymbianFoundation
