Patent ID: 7370221

Claim:
A Central Processing Unit (CPU) frequency adjusting system compnsing: an application level, comprising: a user interface for generating a command signal to adjust a CPU frequency according to an input from a user, and displaying an adjusted CPU frequency; and a Dynamic Link Library for receiving the command signal from the user interface; a driver level, comprising: a driver model for receiving the command signal from the Dynamic Link Library; and a hardware abstraction level, comprising: a flash memory for storing the adjusted CPU frequency; and a Basic Input/Output System (BIOS) for receiving the command signal from the driver model, the BIOS comprising: a frequency adjusting module for adjusting a frequency of a clock generator of a motherboard on which the CPU is mounted according to the command signal, thereby adjusting the CPU frequency; and a data accessing module for storing the adjusted CPU frequency in the flash memory, and reading the adjusted CPU frequency from the flash memory; wherein the driver model and the Dynamic Link Library cooperate to transmit the adjusted CPU frequency to the user interface for displaying the adjusted CPU frequency to the user.
