Description

A system including a plurality of hardware devices and an initialization control method thereof

The present invention relates to a technique for selectively initializing hardware devices included in a system.

In general, electronic devices with a current control function initialize by supplying power to all components when booting. In addition, if it is not used for a certain period of time after booting, some power is cut off or it enters a low power mode to save power.

However, although power consumption after a certain period of time after booting can be reduced in this conventional method, current wasted due to power supply to unnecessary parts during system initialization and booting time due to unnecessary initialization of hardware devices is required. And, when it wakes up from the low power mode to the normal mode again, power is supplied to all parts again and initialized, and unnecessary current and initialization time may be required.

Accordingly, the technical problem to be solved by the present invention is to provide a system and method for selectively initializing a hardware device.

A system including a plurality of hardware devices according to the present invention for solving the above technical problem, a memory for storing grouping information and a group device control table - The grouping information is a predetermined grouping of the plurality of hardware devices into a plurality of groups information grouped according to criteria, and the group device control table includes reuse probability information for each of the plurality of groups after system booting; and a control unit that selectively initializes only hardware devices belonging to a group set to be initialized at the time of system booting according to the plurality of group-by-group initialization setting information set based on the plurality of group-specific reuse probability information.

The reuse probability information for each of the plurality of groups may be obtained by a predetermined algorithm based on at least one of a frequency of use and a usage pattern for each of the plurality of groups for a predetermined period.

The group device control table may further include information on whether to perform predetermined initialization for each of the plurality of groups based on the reuse probability information for each of the plurality of groups.

The group device control table may further include predetermined threshold values for each of the plurality of groups and initialization setting information configured to initialize a group having reuse probability information equal to or greater than a threshold value among the plurality of groups when the system is booted.

An initialization control method of a system including a plurality of hardware devices according to the present invention for solving the above technical problem includes the steps of: storing grouping information and a group device control table in a memory - The grouping information includes the plurality of hardware devices information that is grouped into a plurality of groups according to a predetermined criterion, and the group device control table includes reuse probability information for each of the plurality of groups after system booting; and selectively performing initialization upon system booting of only hardware devices belonging to a group set to be initialized according to the plurality of group-by-group initialization setting information set based on the plurality of group-specific reuse probability information.

According to the present invention, there is an advantage in that it is possible to reduce power consumption and shorten the system initialization time by cutting off power supply to a hardware device having a low usage probability and omitting initialization during system booting.

Then, with reference to the accompanying drawings, the embodiments of the present invention will be described in detail so that those of ordinary skill in the art can easily carry out the present invention.

1 is a block diagram of a system according to an embodiment of the present invention.

Referring to FIG. 1 , a system 1 according to the present invention may include a plurality of hardware devices 10 , a control unit 20 , and a memory 30 .

The plurality of hardware devices 10 may be variously configured according to the system 1 . For example, when the system 1 is a notebook or tablet computer, it may be configured with hardware devices such as a camera, a Bluetooth module, a Wi-Fi module, a speaker, a microphone, a keyboard, and a mouse. When the system 1 is a satellite, various hardware devices constituting the satellite may be included in the system 1 .

The control unit 20 controls the overall operation of the system 1 . The control unit 20 includes a processor, a controller, an arithmetic logic unit (ALU), a digital signal processor, a microcomputer, a field programmable gate array (FPGA), a programmable logic unit (PLU), a microprocessor, or an instruction. ) may be implemented using one or more general purpose computers or special purpose computers, such as any other device capable of executing and responding.

The memory 30 may store various types of information and data related to the operation of the system 1 . In particular, the memory 30 may store the grouping information and the group device control table and may provide it according to the request of the controller 20 . The memory 30 may be implemented as a non-volatile memory device such as a ROM or a flash memory.

Here, the grouping information is information obtained by grouping the plurality of hardware devices 10 according to a predetermined criterion. A plurality of hardware devices 10 existing in the system 1 may be grouped into a plurality of groups by function. For example, when the system 1 is a printer multifunction printer having a facsimile function, a scan function, and a printer function, the hardware devices 10 used for the corresponding function may be grouped according to the facsimile function, the scan function, and the printer function.

A plurality of hardware devices 10 present in the system 1 may be displayed to the user and may be implemented to receive grouping settings from the user. Alternatively, the default mounted hardware device 10 may be grouped in advance when the system 1 is manufactured. In addition, an update patch for recognizing and automatically grouping the hardware device 10 additionally installed in the system 1 or newly commercialized may be supported.

Table 1 shows an example of grouping a plurality of hardware devices according to an embodiment of the present invention. An example of grouping the hardware devices of the system 1 into N device groups is shown, with J in the first functional device group, K in the second functional device group, L in the third functional device group, and the Nth function It is exemplified that M hardware devices are grouped in the device group, respectively.

The number of functional device groups or the number of hardware devices grouped in each functional device group may vary according to the system 1 .

The group device control table may be used when determining whether to initialize hardware devices belonging to each functional device group when the next system 1 is booted.

Table 2 is a diagram illustrating a group device control table according to an embodiment of the present invention.

device group second function
device group 3rd function

… Nth function
device group Reuse Chance
information 12% 60% 30% … 10% threshold 50% 50% 30% … 40% Whether to reset
Setting information Disable Enable Enable … Disable

The group device control table may include group-specific reuse probability information, threshold value, and initialization or not setting information. In the case illustrated in Table 1, the second functional device group and the third functional device group whose reuse probability information is equal to or greater than the threshold are set to Enable initialization at the next system boot, and the first functional device whose reuse probability information is less than the threshold The group and the N-th function device group may be set to not performing initialization (Disable).

Here, the system booting may include all concepts of system initialization due to other reasons, such as a power on reset, a warm reset, and a wakeup from a low power mode.

The reuse probability information corresponds to the probability that the hardware device of the functional device group will be reused after the next system booting. The higher the recent frequency of use, the higher the reuse probability increases, and vice versa, the reuse probability may decrease.

As illustrated in Table 1, the reuse probability information can be expressed as a percentage. According to an embodiment, the reuse probability information may be determined as a recent frequency of use, for example, a frequency of use of a corresponding group for a predetermined time from the current time. In addition, according to an embodiment, reuse probability information may be generated using an algorithm generated by machine learning data collected by hardware device usage frequency and usage pattern for the system 1 as learning data.

In addition, the threshold may be set differently according to each device functional group. The threshold value may be set differently for each device function group according to the characteristics of the system 1 or user selection.

2 is a diagram for explaining a reuse probability calculation algorithm according to another embodiment of the present invention.

2 illustrates an algorithm for calculating reuse probability information using a 2-bit saturation counter (counter value is in the range of 0 to 3). The control unit 20 has a separate counter for each functional device group, and when the function of the corresponding device group is used for a specific time, the counter value increases by 1, and when the function of the corresponding device group is not used for a specific time, the counter value decreases by 1. The controller 20 may set the reuse probability information of the corresponding group to 100% if the counter value is 2 or more, and 0% if it is less than 2. In addition, if the reuse probability information is 100%, the controller 20 may set initialization to be performed at the next system booting, and if the reuse probability information is 0%, may set it to Disable initialization. In this case, the threshold may be set to a value between 100% and 0%.

Table 3 shows that according to the above algorithm, the first functional device group and the second functional device group are set to Enable initialization as illustrated in FIG. 2, and the third functional device group and the fourth functional device group are not initialized. It shows the state set to Disabled.

first function
device group second function
device group 3rd function
device group 4th function
device group counter value 2 3 0 One Reuse Chance
information 100% 100% 0% 0% Whether to reset
Setting information Enable Enable Disable Disable

Of course, in addition to the method exemplified here, it is possible to obtain and apply the reuse probability for each functional device group after the next system boot by various methods.

3 is a flowchart illustrating a method of operating a system according to an embodiment of the present invention.

1 and 3 , first, the controller 20 may store grouping information and a group device control table in the memory 30 . The grouping information and the group device control table may be continuously updated while the system 1 operates.

Thereafter, when the booting procedure of the system 1 is started (S310-Y), the controller 20 loads the grouping information and the group device control table from the memory 30 (S320).

And when the initialization information of the corresponding functional device group is set to 'Enable' (S330-Y), the control unit 20 supplies power to all the hardware devices 10 belonging to the corresponding functional device group. and (S340), and performs initialization (S350).

On the other hand, if the initialization setting information of the corresponding functional device group is set to 'Disable' (S330-N), the control unit 20 supplies power to all hardware devices 10 belonging to the corresponding functional device group. Without supplying, initialization is not performed (S360).

Step (S330), step 340 and step (S350) or step 330 and step (S360) are sequentially performed for all functional device groups included in the group device control table, and for all groups set to perform initialization If initialization is performed (S370-Y), the controller 20 may end the system booting procedure.

On the other hand, if the use of a function of a device group that has not been initialized is requested by group device control table information during system initialization, power may be supplied to devices belonging to the corresponding device group in real time and initialization may be performed at the time of request for use.
