18. 18
Tizen* OS Compliance
• Tizen* OS Compliance is designed to ensure mobile
device implementations and applications work
together
– Mobile device implementations: if implemented to a
profile, a device will provide a consistent behavior defined
by that profile to applications, and provide a consistent user
experience
– https://source.tizen.org/compliance/compliance-
specification
– Applications: if built to this specification, applications will
run on compliant devices which implement the APIs it uses.
Applications MAY be targeted to a specific profile if
necessary
– https://source.tizen.org/compliance/application-compliance
19. 19
Tizen* OS Compliance Platform & Profiles
• The current profile is
– Mobile: Handsets, tablets
• Additional profiles are expected in the future,
possibly including
– IVI: In-vehicle infotainment systems
– TV: DTV/STB/IPTV systems
– Clamshell: Notebook style laptops
– Camera: Cameras
– Printer: Printers
21. 21
Examples of Innovation and Differentiation
• Security
• Camera stack
• Connectivity
• Power Management
22. 22
Tizen* Security
Tizen* takes a layered approach to security, with an innovative
framework that allows platforms to implement a manageable
security solution, and minimizing the attack vectors of malware.
WRT - Web Runtime
• Each application is sandboxed
• Each Application is digitally signed by the developer and by the distributor
(Tizen store)
• Encrypted application is decoded at runtime, not at install
SMACK - Simplified Mandatory Access Control in the Kernel
• Each application has its own SMACK label
• Any access to an object in the system (e.g. contacts database) is checked
against the SMACK rules
Content Security Framework
• Provides privileges necessary to properly protect the device
• APIs to scan applications, device content, URLs used by the applications, etc.
24. 24
Video recorder and View Finder performance
tuning
• Buffer sharing for video recorder
• Dual stream support
Still image capture performance tuning
• Remove unnecessary color convert for still image
capture
• Buffer sharing for still image capture
Tizen* Camera Performance tuning
25. 25
Tizen* OS Connectivity
• The mobile profile is using a Tizen*
specific Telephony stack
– oFono (another open source project) has been
integrated into Tizen and provides a rich set of
features
• Similarly, the NFC solution in Tizen mobile
targets a specific set of NFC hardware
– The Open Source Linux*-NFC (neard) solution
has been adapted to work inside Tizen, and
could be used as an alternative option
Differentiation or Innovation? Integrators have
options!
26. 26
Tizen* OS Power Management
There are multiple energy saving features in
the Linux kernel, at the whole system level as
well as at the individual processor or I/O
device level.
• To get to longer battery life
– Only do needed jobs
– Do the job as fast as possible
– Enter into low power status as much as possible
– Avoid unnecessary wakeup as much as possible

Risk Factors
The above statements and any others in this document that refer to plans and expectations for the third quarter, the year and
the future are forward-looking statements that involve a number of risks and uncertainties. Words such as “anticipates,”
“expects,” “intends,” “plans,” “believes,” “seeks,” “estimates,” “may,” “will,” “should” and their variations identify forward-looking
statements. Statements that refer to or are based on projections, uncertain events or assumptions also identify forward-looking
statements. Many factors could affect Intel’s actual results, and variances from Intel’s current expectations regarding such factors
could cause actual results to differ materially from those expressed in these forward-looking statements. Intel presently considers
the following to be the important factors that could cause actual results to differ materially from the company’s expectations.
Demand could be different from Intel's expectations due to factors including changes in business and economic conditions;
customer acceptance of Intel’s and competitors’ products; supply constraints and other disruptions affecting customers; changes
in customer order patterns including order cancellations; and changes in the level of inventory at customers. Uncertainty in global
economic and financial conditions poses a risk that consumers and businesses may defer purchases in response to negative
financial events, which could negatively affect product demand and other related matters. Intel operates in intensely competitive
industries that are characterized by a high percentage of costs that are fixed or difficult to reduce in the short term and product
demand that is highly variable and difficult to forecast. Revenue and the gross margin percentage are affected by the timing of
Intel product introductions and the demand for and market acceptance of Intel's products; actions taken by Intel's competitors,
including product offerings and introductions, marketing programs and pricing pressures and Intel’s response to such actions; and
Intel’s ability to respond quickly to technological developments and to incorporate new features into its products. The gross
margin percentage could vary significantly from expectations based on capacity utilization; variations in inventory valuation,
including variations related to the timing of qualifying products for sale; changes in revenue levels; segment product mix; the
timing and execution of the manufacturing ramp and associated costs; start-up costs; excess or obsolete inventory; changes in
unit costs; defects or disruptions in the supply of materials or resources; product manufacturing quality/yields; and impairments
of long-lived assets, including manufacturing, assembly/test and intangible assets. Intel's results could be affected by adverse
economic, social, political and physical/infrastructure conditions in countries where Intel, its customers or its suppliers operate,
including military conflict and other security risks, natural disasters, infrastructure disruptions, health concerns and fluctuations in
currency exchange rates. Expenses, particularly certain marketing and compensation expenses, as well as restructuring and asset
impairment charges, vary depending on the level of demand for Intel's products and the level of revenue and profits. Intel’s
results could be affected by the timing of closing of acquisitions and divestitures. Intel's results could be affected by adverse
effects associated with product defects and errata (deviations from published specifications), and by litigation or regulatory
matters involving intellectual property, stockholder, consumer, antitrust, disclosure and other issues, such as the litigation and
regulatory matters described in Intel's SEC reports. An unfavorable ruling could include monetary damages or an injunction
prohibiting Intel from manufacturing or selling one or more products, precluding particular business practices, impacting Intel’s
ability to design its products, or requiring other remedies such as compulsory licensing of intellectual property. A detailed
discussion of these and other factors that could affect Intel’s results is included in Intel’s SEC filings, including the company’s
most recent reports on Form 10-Q, Form 10-K and earnings release.
