To handle complex in-car telematics and infotainment systems, designers are turning to full-featured, protected-mode RTOSs. Despite their sophistication, these systems must satisfy the same timing requirements as older hardware-software solutions. Thanks to "mini-driver technology," small, highly efficient device drivers start executing before the OS kernel is initialized. Defined in the system's boot loader, a mini-driver can respond to a power-up message in a quick, timely fashion and ensure no other messages are lost while the OS boots up. Once the OS has booted, the mini-driver may continue running or it may pass control to a full-featured driver, which can then access any message the mini-driver has buffered. | |
