Design in-vehicle systems that meet strict timing and response requirements for critical functionality — without adding costly redundant hardware. Instant Device Activation provides a “minimal” driver layer that can initialize and communicate with peripheral devices before the operating system is fully operational. This provides the infrastructure needed to quickly respond to power on events and meet strict timing requirements.

The QNX® Instant Device Activation toolkit provides the tools, source, and documentation to help you quickly implement custom boot functionality for your unique environment.

• Deliver Critical Functionality
  
  • Responds to external events, meets critical response times, accesses hardware, and stores data for the full driver
    
  • Immediately responds to power mode management transmitted over the CAN bus
    
  • Continues to run or exits the system seamlessly once control is transitioned to the full driver process — without causing blackout times or losing any data
    
• Reduce Hardware Costs
  
  • Manages data from buses such as MOST and CAN without adding costly hardware
    
  • Boots from a cold or low-power state without auxiliary communications processors to meet timing and response requirements
    
  • Potentially decreases bill-of-materials costs by up to $8 per unit
    
• Customize Your Application
  
  • Provides full source and documentation for easy configuration
    
  • Allows designers to adapt standard polling intervals to meet device timing requirements and define the amount of data stored in the IDA buffer
    
  • Allows designers to determine the optimal driver transition model by specifying when the full driver process takes over
