Description

computer

technical field

The present invention relates to a computer, and in particular to a computer with the function of controlling memory power supply.

Background technique

Random access memory is memory that exchanges data directly with the CPU. Random access memory can be read and written at any time, and the speed is very fast. It is usually used as a temporary data storage medium for operating systems or other programs that are being executed.

As the price of random access memory becomes lower and lower, the random access memory disk becomes more and more popular. The so-called random access memory disk, as the name implies, is to virtualize the random access memory into a disk drive. Among them, the random access memory has the characteristic that the transmission rate is faster than the general traditional hard disk. As a result, the data transfer rate of the random access memory disk is far better than that of the traditional hard disk. In this way, through the ultra-fast data transfer rate of the random access memory, the efficiency of program execution can be greatly accelerated. Therefore, if the operating system files are stored in the random access memory disk to load when booting, it will be far faster than loading the operating system files from the traditional hard disk, thus greatly shortening the time required for booting.

However, after the random access memory is powered off, the data stored on it will also disappear. Therefore, limited by the above characteristics, the data stored in the random access memory disk will also disappear when the power is turned off. Therefore, in most cases, users only store files that do not need to be permanently stored (such as temporary disks) on random access memory disks. In other words, data that cannot be lost when power is turned off (such as operating system files) cannot be stored on the RAM disk.

Contents of the invention

Therefore, an object of the present invention is to provide a computer, which is used to divide the memory of the computer into two types, and continuously supply power to part of the memory of the computer through a system power supply and a battery power supply unit. In particular, faster system performance can be achieved when saving information including operating system files in this part of the memory.

According to an embodiment of the present invention, a computer includes a central processing unit, a chipset, a power supply system, a memory unit and a control module. The chipset is coupled to the central processing unit. The power supply system includes a system power supply and at least one battery power supply unit. The system power supplies power to the computer. The memory unit is coupled to the chipset. The memory unit includes at least one first memory and at least one second memory. The control module includes a management chip and a switching circuit. The management chip is coupled to the chipset. The switching circuit is coupled to the system power supply and the battery power supply unit. Wherein, the management chip controls the switching circuit to select one of the system power supply and the battery power supply unit to supply power to the second memory.

Application of the present invention has the following advantages. It can avoid the loss of data stored in part of the memory due to power failure. Therefore, the data that cannot be lost when the power is turned off can be stored in the internal memory, so that the above data can be accessed quickly. In addition, when storing the operating system in the memory, it will be much faster than loading the operating system file from the traditional hard disk, so the time for loading the operating system can be greatly shortened, thereby speeding up the booting speed.

Detailed ways

Please refer to FIG. 1 , which is a functional block diagram of a computer according to an embodiment of the present invention. The computer memory is divided into two types, and a part of the computer memory is continuously powered through the system power supply and the battery power supply unit. In this way, faster system performance can be achieved when storing information including operating system files in this part of the memory.

The computer 100 includes a central processing unit 110 , a chipset 120 , a power supply system 130 , a memory unit 140 and a control module 150 . Wherein, the memory unit 140 can be a random-access memory (Random-access Memory, RAM) or other types of memory.

A northbridge 121 of the chipset 120 is coupled to the CPU 110 . The power supply system 130 includes a system power supply 131 and at least one battery power supply unit 132 . Wherein, the system power supply 131 is used to supply power to the computer 100 . The memory unit 140 is coupled to the chipset 120 . The memory unit 140 includes at least one first memory 141 and at least one second memory 142 . The control module 150 includes a management chip 151 and a switching circuit 153 coupled to each other. The management chip 151 is coupled to the chipset 120 . The switching circuit 153 is coupled to the system power supply 131 and the battery power supply unit 132 .

The management chip 151 outputs a control signal to the switching circuit 153 to control the switching circuit 153 to select one of the system power supply 131 and the battery power supply unit 132 to supply power to the second memory 142 . Wherein, when the computer 100 is running, the second memory 142 is powered by the system power supply 131 . When the computer 100 is turned off or the system power supply 131 is cut off, the switching circuit 153 switches to the battery power supply unit 132 , thereby enabling the battery power supply unit 132 to supply power to the second memory 142 . In this way, the second memory 142 can be continuously powered by the system power supply 131 and the battery power supply unit 132 , so that the data stored in the second memory 142 will not be lost due to power failure. Therefore, when an operating system is stored in the second memory 142 , the fast access speed of the memory unit 140 can greatly shorten the time for loading the operating system, thereby enabling the computer 100 to have a fast booting speed. Wherein, the operating system may be a Microsoft Windows operating system (Microsoft Windows), Linux, Unix or other operating systems.

The computer 100 further includes a BIOS 160 coupled to a south bridge 122 of the chipset 120 . Wherein, the basic input and output system 160 provides a setting interface for the user to set the attributes of the multiple memory blocks of the memory unit 140 as the first memory 141 or the second memory 142 . In this way, the user can adjust the sizes of the first memory 141 and the second memory 142 according to his needs.

In addition, when the system of the computer 100 is powered on, the BIOS 160 identifies the first memory 141 and the second memory 142 of the memory unit 140 , and only initializes the first memory 141 . In this way, the data stored in the second memory 142 can be prevented from being lost during initialization.

In addition, the management chip 151 may include a monitoring module 152 for continuously monitoring the power storage condition of the battery power supply unit 132 . Wherein, when the system of the computer 100 is powered on, the monitoring module 152 controls the charging and discharging of the battery power supply unit 132 so that the battery power supply unit 132 maintains sufficient power. In this way, the power reserve of the battery power supply unit 132 can be prevented from being insufficient to provide enough power to the second memory 142 . Therefore, the data stored in the second memory 142 can be prevented from being lost due to power failure.

It can be known from the above embodiments of the present invention that the application of the present invention has the following advantages. It can continuously supply power to part of the memory in the computer, thus avoiding the loss of data on the above-mentioned memory due to power failure. Therefore, data that cannot be lost when the power is turned off can be stored on the random access memory disk. In this way, the stored data can be quickly accessed through the high-speed data transmission speed of the memory. In addition, when the operating system is stored in the memory, it will be much faster than loading the operating system files from the traditional hard disk, so the time for loading the operating system when starting up can be greatly shortened, thereby speeding up the booting speed of the computer.
