VxWorks 7 Core Platform OS
Ecosystem Packages Wind River Packages
Package Paradigm for VxWorks 7
3 Years
• New infrastructure for installation, distribution, and deployment of
application packages
• Support for incremental addition or deletion of components
8
Scalability
VxWorks 7 Core Platform OS
Lifecycle of Application is separate from core kernel
• Enables individual apps to be patched or updated at any time,
as needed

VxWorks 7 Core Platform OS
Multiple versions of Packages can coexists in the development tree
• Enables patches or new versions to
be tried out and rolled back when
required

Microkernel Profile
VxWorks Microkernel
Standard VxWorks Kernel
Edge Devices
• Very small kernel (~20 KB)
• Lower safety certification cost
• Fast threading model
• Suitable for multi-core SoC, multiprocessor, or sensors
11
Scalability
VxWorks Microkernel
Standard VxWorks Kernel
• Multi-core with big and small core configurations
• Offload of important or repetitive tasks for maximum
processing efficiency
Designed for Big-Little Core Configurations

Impact Value
Scalability: Reducing Time-to-Market at Lower Cost
Single software platform for small and large applications
Use common technology, lowering
the cost of the BSP, certification,
security, and engineers.
>$1M for companies with more than 5 projects
Patches only when and where
needed Avoid major testing efforts across
the platform, saving $$$. 3 man months for each incident
Frequent updates as technology
and markets evolve
Become competitive without the
risk of breaking fielded devices.
Strategic impact on overall business and profitability

Impact Value
Safety: Reduce Cost by Consolidation of Applications
Run safe and non-safe applications on the same device.
Save big costs in hardware,
maintenance, and inventory
40% reduction in BOM cost, overall savings of up to 60%
Update non-safe applications without recertification of the device.
Allow frequent modification of the device without spending time and money.
At least $500K in savings with strategic competitive edge

Security Safety
Scalability
Designing with “Just Enough Security” Security
21
Flexible implementation to
match the level of threat
All threat scenarios
addressed
Storage (on device)
Environment (where installed)
Access Points (in operation)
Accessing Threat Scenarios Across the Device Lifecycle
Security
22
Boot Run Time Power Down
Design
Prevent malicious code in development
Prevent untrusted
binaries from executing
Prevent malicious attacks in operation
Prevent onboard data access when
at rest
Four Pillars of Security Provided by VxWorks Security

Impact Value
Security: Reduce Cost with Just Enough Security
Comprehensive security solution across major threat environment
Competitive advantage by offering
a solid, secure device
Flexibility in designing minimal set
of security necessary for the device Cost savings as the CPU is only
minimally used for security
