First Claim
Patent Images
1. A method of processor for booting a computing system in which a boot image transmission and device initialization are performed in parallel, the method comprising:
- reading a device initialization code from a main storage medium and writing the device initialization code to an internal random access memory (IRAM);
instructing a direct memory access (DMA) controller to write a boot image that is stored in the main storage medium to a main memory, wherein the boot image is used for booting the computing system;
initializing devices that are used for booting the computing system using the device initialization code written in the IRAM; and
executing the boot image that is written in the main memory.

Abstract
Provided is a method of booting a computing system which performs boot image transmission and device initialization in parallel. For example, using an Internal RAM and direct memory access (DMA), hardware initialization and loading of boot image from a main storage medium to a main memory are performed in parallel, thereby reducing time spent on booting.

8. A terminal comprising:
-
a direct memory access (DMA) controller for writing a boot image stored in a main storage medium to a main memory; and a processor for initializing devices to be used for booting the terminal using device initialization codes stored in an internal random access memory (IRAM), and for executing the boot image, wherein the DMA controller writes the boot image to the main memory and the processor initializes the devices for booting the computer, simultaneously. - View Dependent Claims (9, 10, 11, 12)
