After the command is received, the microcontroller 121 determines what kind of data needs to be replied, and reads the data required by the host system 11 from the flash memory 122, and then sends the data to the random access memory. After 123, the data bus is transmitted to the host system 11 through the data bus, and the loop is continued until the host system 11 executes the instructions required for the booting, and the corresponding data is obtained to complete the booting operation.

Although the booting procedure used by the prior art does complete all the steps of the booting, the waiting time for the host system 11 to communicate with the storage medium 12 is too long, and the waiting time for the microcontroller 121 to wait for the flash memory 122 to find the data is waiting. Too long, so that the user can operate the operating system from the power-on button of the triggering of the computer device 1 to the actual startup. The user must spend too much time waiting. If the user only needs to use the computer device 1 to query the information for a short time, the boot time is often inversely proportional to the user. The long time of use not only makes the user feel that the boot time is very long, but also indirectly causes waste of energy.

Therefore, how to develop a method for increasing the startup speed of an electronic device that can improve the above-mentioned conventional technology is an urgent problem to be solved.

The main purpose of the present invention is to provide a method for increasing the booting speed of an electronic device, and to solve the problem that the conventional host system communicates with the storage medium and waits for the microcontroller to look for data in the flash memory for too long, and must spend too much time waiting for execution. The boot process makes the user feel that the boot time is very long and causes waste of energy.

In order to achieve the above object, a broader aspect of the present invention provides a method for increasing the booting speed of an electronic device. The electronic device includes a host system and a storage medium, and the storage medium includes a controller, a data storage unit, and a data temporary storage unit. The data storage unit has a boot order sorting table, and at least includes the following steps: (a) when the electronic device starts the power supply, the controller pre-loads the boot data corresponding to the boot order sorting table into the data temporary storage unit by the data storage unit in sequence. (b) receiving the boot command transmitted by the host system; (c) the controller uses the boot command sorting table to compare the boot data corresponding to the boot command to transfer the boot data pre-stored in the data temporary storage unit to the boot data Host system.

Some exemplary embodiments embodying the features and advantages of the present invention are described in detail in the following description. It is to be understood that the present invention is capable of various modifications in the various aspects of the present invention, and the description and illustration are in the nature of

The present invention is a method for increasing the booting speed of an electronic device. The applicable electronic device can be, but is not limited to, a computer device. Please refer to the second figure, which is the connection structure between the host system and the storage medium in the electronic device of the present invention. As shown in the figure, the electronic device 2 of the present invention includes a host system 21 and a storage medium 22, wherein the host system 21 can be configured as a motherboard, and the storage medium 22 can include a controller 221 and a data storage unit 222 therein. The data storage unit 223 can be a microcontroller and is connected to the host system 21, the data storage unit 222, and the data temporary storage unit 223, and is mainly responsible for controlling the control unit of the entire storage medium 22.

The data storage unit 222 can be a flash memory, which is connected to the controller 221 and the data temporary storage unit 223, and stores the booting data required for the booting process of the electronic device 2 and a booting instruction sorting table 2221, wherein the booting is performed. In the instruction sorting table 2221, the controller 221 sequentially stores all the booting commands of the host device 21 to the storage medium 22 in the booting process, and the booting materials corresponding to each booting command, which are stored in the data. The location of the data in the storage unit 222, such as: Logical Block Address (LBA), and data length.

The data temporary storage unit 223 can be a random access memory, which is connected to the host system 21, the controller 221, and the data storage unit 222 to temporarily store the boot data, and is controlled by the controller 221 to sequentially the host system 21 The boot data corresponding to the transmitted boot command is transmitted to the host system 21.

Please refer to the third figure and the second figure. The third figure is a flow chart for increasing the power-on speed of the electronic device according to the first preferred embodiment of the present invention. As shown in the figure, first, the power is turned on in the electronic device 2 (power on After the step (step S31), the controller 221 first reads the boot order sorting table 2221 from the data storage unit 222 and stores the boot order sorting table 2221 in the data temporary storage unit 223, and pre-sets the boot order sorting table 2221. The corresponding booting data is sequentially loaded into the data temporary storage unit 223 by the data storage unit 222 (step S32). After the host system 21 transmits a boot command to the storage medium 22, the controller 221 receives the transmitted by the host system 21. The boot command (step S33), and determines whether the boot command transmitted by the host system 21 is the same as the boot command corresponding to the boot command sorting table 2221 (step S34), for example, when the host system 21 transmits The third boot command is C, and the controller 221 needs to query whether the third boot command recorded in the boot command sort table 2221 is also C.

When the result of the determination in the step S34 is NO, it indicates that the electronic device 2 has different booting behaviors due to various factors such as the file format, the division of the storage medium slot, the operating system, and the BIOS upgrade, so the controller 221 will Instantly correct the boot command in the sequence corresponding to the boot command sorting table 2221 (step S35), and then the controller 221 will according to the content of the boot command transmitted by the host system 21, that is, the boot data corresponding to the boot command. The corresponding data location stored in the data storage unit 222, such as: Logical Block Address (LBA), and data length, can be checked by reading a L2P table (Logic to Physical Table). The logic block of the boot command is located in the physical block address corresponding to the data storage unit 222 to obtain the boot data corresponding to the boot command and transmitted to the data temporary storage unit 223 for transmission to the host system. 21 performs a booting process (step S36).

For example, when the third power-on command sent by the host system 21 is C, and the controller 221 checks that the third power-on command is D, the controller 221 immediately responds to the power-on command sorting table 2221. The third power-on command is corrected from D to C (step S35), and then the corresponding boot data is searched for in the data storage unit 222 according to the content of the power-on command C, and transmitted to the data temporary storage unit 223 for transmission to the host system. 21 performs a booting process (step S36).

When the result of the step S34 is YES, the controller 221 can directly store the boot data in the data temporary storage unit 223, and the boot data corresponding to the boot command is transmitted to the host system 221 (step S37). When the data storage unit 222 reads the boot data, the time for waiting for the controller 221 to the data storage unit 222 to find the boot data can be reduced, so that the boot can be completed quickly.

After step S37 or step S36, it is determined whether the booting process of the electronic device 2 has been completed (step S38). When the result is no, step S33 and subsequent steps are repeatedly performed. Conversely, when the result is YES, the boot is over. As for the manner of judging whether the booting process of the electronic device 2 has been completed, the controller 221 determines whether all the booting commands in the booting order sorting table 2221 have been compared (step S34), and once the comparison is completed, the booting procedure is completed. Completed, but the judgment method is not limited to this.

Please refer to the fourth figure, which is a flowchart for increasing the power-on speed of the electronic device according to the second preferred embodiment of the present invention. The flow in this embodiment includes steps S31-S39, wherein steps S31-S33, S34, and S36-38 are performed. The same as the first preferred embodiment, the description will not be given here.

The difference between this embodiment and the first preferred embodiment is that when the result of the determination in step S34 is NO, the controller 221 does not immediately correct the boot command in the order corresponding to the boot command sorting table 2221, but will boot. The power-on command corrected in the order corresponding to the command sorting table 2221 is recorded and stored first (step S35'), until step S38 determines that the booting process of the electronic device 2 has been completed, the controller 221 sorts according to all stored commands regarding the power-on command. The table 2221 corresponds to the contents of the boot command corrected in the order, that is, all the data stored in the step S35', and the contents of the boot command sorting table 2221 are updated once with the data (step S39).

In summary, the method for increasing the boot speed of the electronic device in the present case can be received by the host system by pre-loading the boot data corresponding to the boot order sorting table into the data temporary storage unit in sequence by the data storage unit. After the power-on command is transmitted, the boot data stored in the data temporary storage unit corresponding to the boot command can be directly transmitted to the host system, and the boot data can be read without waiting for the data storage unit to be read. The controller goes to the data storage unit to find the time of the boot data, so that the electronic device can be quickly turned on.

This case has been modified by people who are familiar with the technology, but it is not intended to be protected by the scope of the patent application.
