The application provides a temperature increasing device and a temperature increasing method. The temperature increasing device is arranged on a motherboard including at least one system element. The temperature increasing device includes a power supply module and a controller After the power supply module is triggered, the power supply module outputs an enable signal to the system element and the controller, the controller detects whether the system element operates according to a preset power-on action, if the controller determines that the system element does not operate according to the preset power-on action, the controller outputs an electric signal to enable the temperature of the system element to increase, and when the temperature of the system element is increased to an extent that the controller determines that the system element is capable of operating according to the preset power-on action, the controller stops outputting the electric signal.

Temperature increasing device and temperature increasing method

A method for controlling the fan speed by detecting different power supplies of a mobile electronic device is proposed. When an external power source is used for mobile electronic device and detected by the embedded controller, the first fan control table is used to control the fan speed to increase the heat dissipation capability of the mobile electronic device. When battery power is used as the power source and detected by the embedded controller, a second fan control table is used to control the fan speed to extend the battery life. The first fan control table and the second fan control table become the relation control table between the temperature of the processor and the fan speed or the relation fan control table between the temperature of the processor and the input voltage of the fan for controlling the fan speed according to the temperature of the processor.

Method for controlling fan speed

An additional data transmission channel is provided between the north bridge chip and the system memory when the graphic accelerator is integrated into the north bridge chip. The additional data transmission channel can be similar to the existent data transmission channel between the north bridge chip and the system memory for providing extensive data transmission bandwidth. Alternatively, the additional data transmission channel can be specific to the communication between the graphic accelerator in the north bridge chip and the frame buffer in the system memory.

Core logic chip conducting multi-channel data transmission

A control chip supporting a plurality of buses and control chip set thereof is provided. A control chip supporting a plurality of buses chooses a type of bus for complying with another control chip based on the bus type thereby, wherein a device and a driving circuit are included. The device generates required controlling timings based on selection pins. The driving circuit enables required transmitting direction of pins based on selection pins per se.
