Instant Device Activation (IDA) allows in-vehicle systems to perform intelligently even before the OS is operational.
Code is directly linked into the startup component of the boot loader. In this way it can perform all the necessary functions, such as responding to external events, meeting critical 50-millisecond startup response times, accessing hardware, and storing data for use by the full driver. For example, a system can be configured to provide immediate response to power-mode messages transmitted over the CAN bus.
IDA allows system developers to manage data from the CAN bus without adding costly hardware. Conventional OS implementations often take several seconds to boot up from a cold or low-power state, requiring auxiliary communications processors to meet timing and response requirements. Using QNX IDA technology, this problem can be solved in software, eliminating hardware components and decreasing bill of material (BOM) costs.
