Thinking about making a switch to the new generation of multi-core processors from companies like Broadcom, Freescale and Intel but concerned about the complexity associated with migrating from a uni-processing to multi-processing model?

QNX Software Systems is the only RTOS vendor that offers a comprehensive support and a clean migration strategy from a uniprocessing to multiprocessing environments with OS and development tools specifically for multi-core systems - QNX Neutrino® RTOS and QNX Momentics® development suite:

• QNX Neutrino RTOS provides the foundation developers need to port legacy code, develop new applications, and realize the full performance benefits that multi-core processors have to offer
• QNX Momentics® development suite provides the tools that developers need to develop, debug and optimize multi-core systems
• Together these create the QNX fully integrated multi-core solution - with support for AMP, SMP, BMP and multi-core capable development tools, QNX provides the ideal balance between performance, scalability, and ease of migration

Technology overview

• QNX is the market leader with the only full multi-core solution — supports symmetric (SMP) bound (BMP) and asymmetric (AMP) multiprocessing models
  
• Proven, reliable multiprocessor capable OS - QNX Neutrino RTOS has been multiprocessor capable since 1997
  
• Faster time to market for multi-core applications
  
  • reuse existing applications
    
  • multi-core debugging and optimization tools
    
  • SMP and BMP provide full visibility of all application processes and system resources
    
• Scalable - symmetric and bound multiprocessing scale seamlessly beyond twprocessors
  
• Supported by QNX Momentics multi-core capable development tools
  
  • Application profiler can be used to isolate processing bottlenecks and find candidates for multi-threading and parallel operations
    
  • System profiler can be used to see processing load on each core, monitor inter-core communication and detect resource contention to ensure optional performance on multi-core processors
    
  • Source level debugging on all cores
    

Symmetric multiprocessing

• Scale with subsequent generations of multi-core processors
  
  • Migrate in lock step as processors move from two cores to four and beyond
    
  • Transparent scaling with no need trecode applications
    
• Boost performance with near linear improvements
  
  • QNX Neutrino RTOS is the only commercial RTOS to support true SMP
    
  • Any thread in any process can be scheduled on any processor
    
• Transparent management of shared resources
  
  • Single instance of QNX Neutrino RTOS is aware of all resources
    
  • Unified management of memory, interrupts, I/O
    
• Supports x86, PowerPC and MIPS multi-core and multiprocessing architectures
  

Bound multiprocessing

• Simplify migration
  
  • Run existing applications in Bound mode without modification
    
  • Develop new applications in SMP mode
    
  • Run both on a single platform
    
• Bind applications to specific processors
  
  • Full determinism and control, dedicate processing where needed
    
  • Maximize performance
    
• Focus on application development
  
  • Transparent management of shared resources
    
  • Seamless migration from dual to multi-core processors
    
• Load balancing
  
  • OS controlled dynamic or static load balancing
    
  • Tools toptimize load balancing
    

Asymmetric multiprocessing

• Run different instance of QNX Neutrino on each cores
  
• Preserve legacy operation
  
• QNX Transparent Distributed Multiprocessing for communication between cores
