SYSTEM FOR EXECUTING CODE DURING OPERATING SYSTEM INITIALIZATION

摘要

A system for executing a code during OS(Operating System) initialization is provided to serve a request like an I/O(Input/Output) request while satisfying a strict condition like timing requirement requested from a vehicle telematics system. A CPU(202) executes instructions. A memory(210) communicates with the CPU and stores the instructions. An OS(212) is stored in the memory, manages the result of a computer system, and includes a kernel mode. At least one peripheral(240) communicates with the CPU and generates the I/O request. A boot module(220) communicates with the CPU and the memory, and loads the OS to the memory. A mini-driver(230) is stored in the memory and serves the I/O request generated before the boot module loads the OS to the memory. The boot module includes an IPL(Initial Program Loader) executing starting power in the code, an initial program loading the OS to the memory, and a kernel initializing module initializing the kernel module.
