Background technique

Hard disk is the largest capacity but also the slowest data storage medium. Before actually writing data, it is often necessary for the host to issue an access request, so that the hard disk can decide whether to read or write to the hard disk according to the access request. In order to save power, the hard disk will gradually turn off the power of each module in the hard disk after being idle for a period of time, so as to enter the idle mode. However, even when the hard disk is not busy, the host will still access the hard disk at regular intervals. It is completely unable to play the role of idle mode to save power.

Therefore, how to design a new hard disk power-saving method and hard disk power-saving device, so that the hard disk can enter the idle mode without being affected by fixed access requirements when the operation is infrequent, so as to achieve the power-saving effect, is for This is a problem that the industry needs to solve urgently.

Detailed ways

Please also refer to FIG. 1 , which is a block diagram of a computer system 1 according to an embodiment of the present disclosure. The computer system 1 can be a desktop computer or a notebook computer. The computer system 1 includes a hard disk power saving device, a central processing unit 12 , a memory 14 and a power module 16 .

The hard disk power saving device includes a hard disk 100 , a hard disk filter module 102 and a detection module 104 . Among them, the central processing unit 12 , the memory 14 , the hard disk filter module 102 and the detection module 104 are the cores of the computer system 1 that actually perform data and calculation processing. Due to the low access speed, the hard disk 100 is only responsible for storing data that is not used in real time. The power module 16 supplies the power required by the core of the computer system to operate.

When the core of the computer system 1 is in operation, the central processing unit 12 mainly performs calculations and processing on data, and performs fast data access through the memory 14, so as to temporarily store the data to be processed and processed in the memory 14 in. The memory 14 is a random access memory or a non-volatile memory in one embodiment. However, when the central processing unit 12 wants to store data into the hard disk 100 , it still needs to write the writing data 11 into the hard disk 100 through the memory 14 .

The time interval for the core of the computer system 1 to perform any two access procedures on the hard disk 100 is the waiting time interval, which means the time for the hard disk 100 to wait for data access. The hard disk 100 has an idle mode, which can be entered when the hard disk 100 is not accessing data, so as to save power. However, the time interval for the hard disk 10 to be idle to enter the idle mode, that is, the start time interval of the idle mode, may be as long as 1 second. But even when the computer system 1 is infrequently operating, the computer system 1 will still write to the hard disk 100, so that the hard disk 10 cannot enter the idle mode or the time for entering the idle mode is very short, and therefore it will be impossible to achieve it by the idle mode. Power saving effect.

The hard disk filtering module 102 is used for receiving the writing data 11 transmitted by the central processing unit 12 through the memory 14 . The detection module 104 is connected to the power supply module 16, the central processing unit 12, the memory 14, the hard disk filter module 102 and the hard disk 100, to detect whether the data access frequency of the computer system 1 exceeds a set value, and to detect the waiting time Whether the interval exceeds the idle mode start interval.

Through the connection of the central processing unit 12, the memory 14, the hard disk filter module 102 and the hard disk 100, the detection module 104 can judge whether the system is too busy, or whether the hard disk 100 has been accessing data, and thereby determine the performance of the computer system 1. Whether the data access frequency exceeds the set value. The method of using the detection module 104 to determine whether the system is too busy is a known technology, such as the detection module in Windows 7, so the scope of the present invention is not limited. And through the time interval between every two accesses of the hard disk 100 by the computer system 1 , that is, the waiting time interval, it can be judged whether the start time interval of the idle mode is exceeded.

When the detection module 104 judges that the data access frequency does not exceed the set value and the waiting time interval exceeds the start time interval of the idle mode, the hard disk filter module 102 stores the written data 11 in the temporary storage location. In one embodiment, the temporary storage location can be the internal memory 14 itself, that is, the hard disk filter module 102 does not write the written data 11 to the hard disk, but makes the internal memory 14 continue to store the written data 11 . In another embodiment, the hard disk filtering module 102 may include a data buffer (not shown), and the temporary storage location is actually located in the data buffer for temporary storage in the temporary storage location. After a time interval or the temporary storage position of the internal memory 14 is filled with the data 11, the data in the internal memory is written into the hard disk, wherein the time interval is a set value and the size of the temporary storage position of the internal memory can also be a set value.

It should be noted that the above-mentioned hard disk filter module 102 can be implemented by hardware or software. Generally speaking, if the temporary storage location is the internal memory 14 itself, the hard disk filter module 102 can be realized by a piece of software, and when the hard disk filter module 102 itself includes The data buffer is implemented by hardware, but this does not limit the scope of the present invention. Before the function of the filter module is executed, the detection module can detect whether the power supply of the power supply module 16 is sufficient, and when the power supply is not sufficient, the function of the filter module is not executed and the write data 11 is directly written into the hard disk 100 in order to avoid data loss.

And when the detection module 104 judges that the data access frequency does not exceed the set value and the waiting time interval does not exceed the idle mode start time interval, it means that the hard disk is busy writing, so the filtering module does not perform its function and will The data written in the memory is directly written to the hard disk. The idle mode start time has not been exceeded

In the above-mentioned embodiment, the hard disk power saving device can temporarily store the written data 11 in the temporary storage position of the memory 14 when the computer system 1 is not busy, instead of writing directly to the hard disk 100, so that the hard disk 100 can be waiting After the time interval exceeds the initial time interval of the idle mode, it enters the idle mode smoothly and prolongs the time that the hard disk is in the idle mode, so as to achieve the power saving effect and greatly reduce the power consumption. After the computer system meets a condition, execute step 203 to write the write data into the hard disk, wherein the condition of the computer system is that the write data is stored in the temporary storage location after a set time interval or the temporary storage of the internal memory 14 The location is filled with write data 11 . The set time interval is a set value and the size of the temporary memory location can also be a set value.

And if the detection module 104 judges that the data access frequency exceeds the set value, which means that the computer system 1 is in a busy state, the written data 11 is directly written into the hard disk 100 from the memory 14 without activating the function of the filter module.

Through the connection between the detection module 104 and the power supply module 16, the detection module 104 can further detect whether the power supply of the power supply module 16 is sufficient, and when the power supply is insufficient, the hard disk filter module 102 will write the data 11 directly from the memory 14 Write to the hard disk 100.

By detecting the power supply module 16, the hard disk power saving device can write all temporarily stored data to be written and the newly received write data 11 into the hard disk 100 when the power supply is insufficient, so as to avoid power failure when the power supply cannot be supplied. The data is lost and cannot be actually written.

Please refer to Figure 2. FIG. 2 is a flow chart of a hard disk power saving method according to another embodiment of the present disclosure. The hard disk power-saving method is applicable to the hard disk power-saving device in FIG. 1 , and includes the following steps: In step 201, the memory is used to receive the writing data transmitted from the central processing unit 12 . In step 202, the detection module is used to determine whether the power supply of the power module 16 is insufficient. When the power is insufficient, step 203 is executed to write the writing data 11 into the hard disk 100 .

When the power supply is sufficient, in step 204, the detection module is used to determine whether the data access frequency of the computer system 1 is greater than a set value. When the data access frequency is greater than the set value, step 203 is executed to write the writing data 11 into the hard disk 100 . When the data access frequency is not greater than the set value, step 205 is executed, and the detection module is used to determine whether the waiting time interval exceeds the idle mode start time interval. When the waiting time interval does not exceed the start time interval of the idle mode, step 203 is executed to write the writing data 11 into the hard disk 100 . When the waiting time interval exceeds the start time interval of the idle mode, in step 206, the filter module is activated to store the written data in the temporary storage location in the internal memory. After the computer system meets a condition, execute step 203 to write the write data into the hard disk to prolong the time that the hard disk is in an idle mode, wherein the condition of the computer system is that the write data is stored in the temporary storage location after a set time Time intervals or temporary storage locations in memory 14 are filled with written data 11 . The set time interval is a set value and the size of the temporary memory location can also be a set value.

It should be understood that, unless the order of the steps mentioned in this embodiment is specifically stated, the order of the steps can be adjusted according to actual needs, and can even be executed simultaneously or partly simultaneously.

It can be seen from the above embodiments of the present disclosure that the advantage of applying the present disclosure is that when the data access frequency of the computer system does not exceed the set value and the waiting time interval exceeds the idle mode start time interval, the written data is temporarily There is a temporary storage location of the internal memory, and the action of writing to the hard disk is performed after a time interval or the temporary storage location of the internal memory is filled with written data 11, so as to extend the time of the hard disk idle mode and achieve power saving effect.

Although the present disclosure has been disclosed above in terms of implementation, it is not intended to limit the present disclosure. Any skilled person familiar with this technology may make various modifications without departing from the spirit and scope of the present disclosure. and retouching, so the scope of protection of the disclosure should be based on the content defined in the claims.
