Optimized for Multi-core

Realize the benefits of embedded multi-core technology with the real-time operating system (RTOS) that's fully multi-core enabled. VxWorks® features asymmetric multiprocessing (AMP), symmetric multiprocessing (SMP), mixed AMP and SMP modes, and multiple SMP instance support within the RTOS, network, and middleware stacks, plus development tools that provide many flexible configuration options to meet your multi-core requirements.

Endless Multi-core Architecture Options

The VxWorks RTOS supports many innovative multi-core configuration options, delivering unprecedented architectural flexibility. Choose between AMP, SMP, multiple SMP instances, or combinations of AMP and SMP to best meet your application and platform requirements. You can also implement an optimized virtualization solution with guest OS support for Wind River Hypervisor that is provided out of the box with VxWorks.

VxWorks AMP
For small independent deterministic tasks, you can construct systems running the same or multiple copies of VxWorks, each handling different tasks and communicating within themselves with no shared resources.

Key Features Details
Multiple instances of VxWorks AMP configurations, including multiple instances of VxWorks and other operating systems
TIPC and Wind River® MIPC internode communication Out-of-the-box solutions for inter-core communication for AMP configurations
Shared memory, devices, virtual consoles, and hardware partitioning Ready-to-use device and resource sharing, saving development time and money versus home-grown solutions
Boot support for AMP systems Hardware bring-up, boot support, and initial configuration for AMP-based VxWorks systems
AMP debugging Specialized support provided in Wind River Workbench for multi-OS technology (including multiple instances of VxWorks RTOS)

VxWorks SMP
Build next-generation multi-core devices leveraging VxWorks SMP support, which maintains the same key RTOS characteristics of performance, small footprint, high reliability, and determinism as VxWorks running on single-core processors.

Key Features Details
Multitasking True concurrent execution of tasks and interrupts
Concurrent task scheduling A priority-based preemptive scheduler that manages the concurrent execution of tasks and automatic load balancing on different CPUs
Mutual exclusion Specialized mechanisms for precise synchronization between tasks and interrupts received simultaneously on different CPUs
CPU affinity The ability to assign specific tasks or interrupts to a specific CPU—useful for locking down tasks and processes to a single core
Simulation capability Development of SMP applications that can begin without physical hardware; SMP simulators are provided with all standard uniprocessor VxWorks installations as an introduction to the SMP product
Enhanced hardware support Performance optimizations and expanded support for multi-core processors from leading silicon manufacturers
Support in all VxWorks market-specific platforms
  • Wind River General Purpose Platform
  • Wind River Platform for Automotive Devices
  • Wind River Platform for Consumer Devices
  • Wind River Platform for Industrial Devices
  • Wind River Platform for Medical Devices
  • Wind River Platform for Network Equipment

VxWorks Mixed Mode AMP and SMP
When your platform would be best served by multitasking with both dedicated resources and heavy processing tasks, mixing SMP with multiple AMP instances could be your best solution.

Key Features Details
Consolidation Mixed mode allowing the combination of high processing and independent deterministic tasks in one multi-core platform

VxWorks SMP Any-to-Any (Cores M to N)
If you require redundancy with hot backup capability or partitioning based on CPUs, VxWorks' unique SMP M2N configuration can help you achieve your multi-core goals. This configuration allows you to run multiple VxWorks SMP operatingsystem instances across dedicated core groupings. The number of cores for each SMP instance does not have to be the same, which allows you to dedicate core groupings as required by your application and high availability needs.

Key Features Details
Multiple VxWorks SMP operating system instances Run next to each other, each instance can include a different number of cores
Higher performance across more than eight cores Multiple schedulers, one for each SMP instance, provide maximum performance across multiple eight-core partitions
