Problems solved by technology

However, after the power is restored, the computer system automatically uses the soft-on method, which must go through a complicated software boot process, which makes the user wait for a long time.
In addition, it is more likely that the computer cannot be restarted due to an error in the execution of the software boot program.

Embodiment Construction

[0042] Please refer to figure 1 , is a functional block diagram of the power-on signal generating device of the first preferred embodiment of the present invention. The power-on signal generating device 1 is set in a computer device (not shown), and is coupled to a computer system 2, such as a Southbridge chipset. The power-on signal generating device 1 can control the computer system 2 to operate when the power supply of the computer device is restored, so as to achieve the purpose of power-on.

[0043] Such as figure 1 The power-on signal generator 1 includes a power detection circuit 10 and a pulse generation circuit 12, wherein the power detection circuit 10 is used to detect a power signal Vi and output a power signal S1. The pulse generation circuit 12 is coupled to the power detection circuit 10 and the computer system 2. It receives a power-on signal S1 from the power detection circuit 10, and outputs a power-on signal S2 to the computer system 2 according to the pow...

Abstract

The invention relates to a starting-up signal generating device which is coupled to a computer system for controlling the starting up of the computer; the starting-up signal generating device comprises a power supply detection circuit and a pulse generation circuit; wherein the power supply detection circuit is used for detecting a power supply signal and outputting a multi-voltage signal; the pulse generation circuit is coupled to the power supply detection circuit and the computer system for receiving the multi-voltage signal and outputting a starting-up signal to the computer system according to the multi-voltage signal. The starting-up signal generation device utilizes a hardware line to lead the computer system to start up automatically after multi-voltage operation is carried out without software control, the full-hardware structure and the line thereof have simple structure and low cost; meanwhile, when power supplying is restored, the computer system can achieve automatic starting-up rapidly by in the invention; in addition, the error caused by software starting-up program execution can be improved, and the problem of being incapable of re-starting can not caused.

Description

technical field [0001] The invention relates to a starting signal generating device, in particular to a starting signal generating device which can restart the computer system after the computer system is powered on again. Background technique [0002] The computer of the X86 system is proposed by Intel (Intel), and its power supply adopts the ATX specification. In addition, the computer of the X86 system can provide the function of software shutdown (soft-off). At the same time, it also includes the functions of timing startup, data ringing startup and multiple startup functions, such as using keyboard, mouse, network startup, etc., and conforms to ACPI ( Advanced Configuration and Power Interface). [0003] ACPI is a high-performance computer configuration and power management technology, which is used to provide a high-performance configuration and power management function for computer systems, thereby making power applications more economical and efficient. In terms o...
