Abstract

A status signal displaying system includes a motherboard, a micro-controller and a display device. The motherboard includes a central processing unit and a plurality of status signal generating circuits for generating status signals. The micro-controller is electrically connected to the status signal generating circuits. The display device is electrically connected to the micro-controller. The status signals are processed by the micro-controller, and the processed status signals are directly transmitted to the display device for display without being processed by the central processing unit.

Claims

1. A status signal displaying system comprising:

a motherboard comprising a central processing unit and a plurality of status signal generating circuits for generating status signals;

a micro-controller electrically connected to the status signal generating circuits; and

a display device electrically connected to the micro-controller, wherein the status signals are processed by the micro-controller, and the status signals are directly transmitted to the display device for display without being processed by the central processing unit.

2. The status signal displaying system according to claim 1 wherein the micro-controller comprises:

a signal processing unit for converting the status signals into corresponding display signals; and

a display processing unit for receiving the display signals and outputting the display signals to the display device for display.

3. The status signal displaying system according to claim 1 wherein the status signals are periodically displayed on the display device.

4. The status signal displaying system according to claim 1 wherein the display device further comprises at least one control button, and by triggering the control button, the micro-controller outputs a corresponding status signal to the display device for display.

5. The status signal displaying system according to claim 1 wherein the status signal includes a core voltage of the central processing unit.

6. The status signal displaying system according to claim 1 wherein the status signals include a core clock reference voltage, which is in direct proportion to a frequency of a core clock of the central processing unit.

7. The status signal displaying system according to claim 1 wherein the status signals include a fan'"'"'s rotating speed signal.

8. The status signal displaying system according to claim 1 wherein the status signals include a temperature signal that is outputted from the temperature detecting unit.

9. The status signal displaying system according to claim 1 wherein the micro-controller and the display device are both disposed outside the motherboard.

10. The status signal displaying system according to claim 1 wherein the micro-controller is disposed on the motherboard but the display device is disposed outside the motherboard.

11. The status signal displaying system according to claim 1 wherein the micro-controller and the display device are both disposed on the motherboard.

12. The status signal displaying system according to claim 1 wherein the motherboard further comprises a north bridge chip, a south bridge chip, a memory and a graphic processing unit, and the status signal generating circuits generate the status signals by detecting the north bridge chip, the south bridge chip, the memory or the graphic processing unit.
