Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the invention.
The present invention provides a method for allocating board resources, and referring to fig. 1, fig. 1 is a schematic flow diagram of a first embodiment of the method for allocating board resources according to the present invention.
While the logic sequence is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown or described here. For convenience of description, the following omits the execution of the main body to describe various steps of the board resource allocation method. The board card resource allocation method comprises the following steps:
step S110, obtaining the number of layers to be displayed and the maximum board card resource number corresponding to each display unit.
Specifically, the number of layers to be displayed and the maximum board card resource number corresponding to each display unit are obtained.
It should be noted that each display unit has the same or different number of layers to be displayed, for example, the video wall has three display units, namely a display unit 1, a display unit 2, and a display unit 3, where the number of layers to be displayed of the display unit 1 is 2, and the number of layers to be displayed of the display unit 2 and the display unit 3 is 0.
It should be noted that the board resources are determined by the hardware conditions of the boards, and therefore, the maximum number of board resources is fixed.
Step S120, determining whether the sum of the number of the layers to be displayed is less than or equal to the maximum board card resource number.
Specifically, whether the sum of the number of layers to be displayed is less than or equal to the maximum board card resource number is judged. It should be noted that, due to the display requirement, the sum of the number of layers to be displayed is greater than, less than or equal to the maximum board card resource number.
Step S130, if yes, allocating board card resources for each layer to be displayed.
Specifically, if the sum of the number of the layers to be displayed is less than or equal to the maximum number of board card resources, which indicates that the board card resources meet the display requirements of all the layers to be displayed, the board card resources are allocated to each layer to be displayed. For example, eight layers are currently in a display state, namely layer 1, layer 2, layer 8230, and layer 8, and the maximum number of board card resources is eight, at this time, two layers to be displayed need to be displayed, and then, under the condition that the number of currently displayed layers is equal to the maximum number of board card resources, board card resources cannot be allocated to the two layers to be displayed, and at this time, displayed layers (layer 1, layer 2, layer 8230; two layers in layer 8) are required to make way of board card resources for new layers; for another example, when six layers are currently in a display state, namely layer 1, layer 2, \8230 \ 8230;, and layer 6, and the maximum number of board card resources is eight, at this time, two layers to be displayed need to be displayed, and then, when the number of layers of the current display image is smaller than the maximum number of board card resources, board card resources are directly allocated to the layers to be displayed.
Further, if yes, after the step of allocating the board card resource to each layer to be displayed, the method includes:
step a, displaying each layer to be displayed based on each board card resource.
Specifically, each layer to be displayed is bound with each board card resource, so that each layer to be displayed is displayed through each display unit based on each board card resource.
In the embodiment, the number of layers to be displayed and the maximum board card resource number corresponding to each display unit are obtained; judging whether the sum of the number of the layers to be displayed is less than or equal to the maximum board card resource number or not; and if so, distributing board card resources for each layer to be displayed. The board card resources are distributed according to the sum of the number of the layers to be displayed, the fixed number of board card resources are not distributed to each display unit, and flexibility in board card resource distribution is improved.
Further, referring to fig. 2, a second embodiment is proposed based on the first embodiment of the board resource allocation method of the present invention, and the method further includes:
step S240, after the displayed layer in each display unit is displayed, releasing the board card resource corresponding to the layer.
Specifically, after the displayed layer in each display unit is displayed, the board card resource corresponding to the layer is released to vacate a position for a new layer to be displayed. It can be understood that the displayed layers occupy certain board resources, and one displayed layer corresponds to one board resource, for example, the board 1 has 8 board resources, and can provide a display basis for 8 layers in the display unit. Referring to fig. 3, board resources 1 and 4 have been allocated to the display unit 1, board resources 5 have been allocated to the display unit 2, board resources 7 and 8 have been allocated to the display unit 3, and board resources 2 and 3 are in an unallocated state and belong to remaining board resources; after the board resources 5 are released, the board resources 5 are changed from the state allocated to the display unit 2 to the remaining board resources.
Further, after the step of determining whether the total number of the layers to be displayed is less than or equal to the maximum board card resource number, the method further includes:
and b, if not, acquiring a layer display sequence.
Specifically, if the sum of the number of the layers to be displayed is greater than the maximum board card resource number, it indicates that the display of the layers to be displayed cannot be completed at one time through each display unit, and at this time, the layer display sequence is obtained.
And step c, discarding the layer to be displayed with the ranking larger than the maximum board card resource number in the layer to be displayed based on the layer display sequence.
Specifically, based on the layer display sequence, the layers to be displayed with the ranking greater than the maximum board card resource number in the layers to be displayed are discarded, so that each display unit can complete the display of the layers to be displayed at one time. For example, the maximum board card resource number is 8, the total number of layers to be displayed is 9, and since only 8 layers to be displayed can be displayed, the layer to be displayed with the ranking of 9 is discarded, so that the layer to be displayed with the ranking of 8 is displayed.
It should be noted that the purpose of discarding the layer to be displayed ranked at 9 is to avoid displaying the layer to be displayed in this round of display, for example, to hide the display of the layer to be displayed, rather than directly not displaying the layer to be displayed.
In this embodiment, after the display unit finishes displaying the layers, the board card resources corresponding to the layers are released, so that the layers to be displayed are displayed by using the released board card resources, and when the sum of the numbers of the layers to be displayed is greater than the maximum number of board card resources, the layer display order is obtained, and the layers to be displayed are displayed through the layer display order, thereby avoiding the problem of board card resource competition (for example, the ranked layers to be displayed need to be preferentially allocated with board card resources) caused by insufficient board card resources when the sum of the numbers of the layers to be displayed is greater than the maximum number of board card resources.
Further, referring to fig. 4, a third embodiment is provided based on the first embodiment of the board resource allocation method of the present invention, where before the step of allocating board resources to each layer to be displayed, the method includes:
step S330, acquiring the number of the current available board card resources;
step S340, if the number of the currently available board card resources is smaller than the total number of the layers to be displayed, recovering the board card resources corresponding to the displayed layer according to a preset recovery rule.
Specifically, the number of current available board card resources is obtained; and if the number of the current available board card resources is less than the sum of the number of the layers to be displayed, recovering the board card resources corresponding to the displayed layers according to a preset recovery rule. It should be noted that, the preset recovery rule is a rule for recovering board card resources, where the recovered board card resources, that is, the board card resources occupied by the layer are released to the currently available board card resources to release the occupation of the layer, in an implementation manner, the board card resources are recovered according to a principle of "first in first out" (preferentially recovering the board card resources that are first occupied in the currently occupied board card resources), so as to complete the display of the layer to be displayed. For example, when the board resources corresponding to the layers are recovered, the recovery order is generally determined by using the display priority, that is, the recovery order of the board resources corresponding to the layer is determined by the time order corresponding to the layer operated by the user last time. It can be understood that the higher the display priority, the later its corresponding recycling order; the lower the display priority, the earlier the corresponding reclamation order. For example, the displayed layers are layer 1, layer 2, \8230 \ 8230;, and layer 8, and the recovery sequence thereof is layer 1> layer 2> \8230; > layer 8, that is, layer 1 is at the bottom layer in 8 layers, layer 8 is at the top layer in 8 layers, at this time, the board resource corresponding to layer 1 is recovered first, and the board resource corresponding to layer 8 is recovered last.
It should be noted that, besides acquiring a plurality of layers to be displayed at a time, there is also a case where one layer to be displayed is acquired at a time, and at this time, board card resources do not need to be recovered before board card resources are allocated or before layer display is completed.
Before the step of obtaining the current available board card resource number, the method includes:
and d, marking the distributed board card resources so as to determine the number of the current available board card resources through the marks.
Specifically, the allocated board resources are marked, and the number of the currently available board resources is determined by the mark, that is, the difference between the maximum number of the board resources and the number of the marked board resources is the number of the currently available board resources. It can be understood that, among the board card resources, the board card resources that are not marked are the currently available board card resources, and the corresponding board card resource number is the currently available board card resource number. For example, referring to fig. 5, the board resources 1, 3, 4, and 7 are allocated board resources, and the number of allocated board resources is known to be 4 by marking the board resources; the board card resources 2, 5, 6 and 8 are currently available board card resources, and the number of currently available board card resources is known to be 4; the allocated board resources 1, the board resources 3, the board resources 4 and the board resources 7 are known as the allocated board resources, and the total board resources are known as the board resources 1, the board resources 2, the board resources 3, the board resources 4, the board resources 5, the board resources 6, the board resources 7 and the board resources 8, the board resources 2, the board resources 5, the board resources 6 and the board resources 8 are currently available board resources, that is, the allocated board resources are 4, the total board resource number (maximum board resource number) is 8, and the difference between 8 and 4 is 4, and it is known that the currently available board resources are 4.
In the embodiment, the number of the current available board card resources is obtained by marking the allocated board card resources, the number of the board card resources to be recovered is determined according to the sum of the number of the current available board card resources and the number of the layers to be displayed, so that the layers to be displayed are displayed, the allocation of the board card resources required by the layer display is performed by using a recovery mechanism, and the layer display efficiency is improved.
Further, referring to fig. 6, a fourth embodiment is proposed based on the third embodiment of the board resource allocation method of the present invention, and includes:
step S440, when the layer display position conversion operation is detected, adjusting the display position of the displayed layer corresponding to the layer display position conversion operation on the display unit, so that the displayed layer is located on the top layer of the remaining displayed layers in the display unit.
Specifically, when a layer display position transformation operation (such as a moving operation, a clicking operation, and the like) is detected, the display position of the displayed layer corresponding to the layer display position transformation operation on the display unit is adjusted, so that the displayed layer is located at the top layer of the remaining displayed layers in the display unit. It can be understood that, in one display unit, if a plurality of layers exist at the same time and the number of pixels occupied by the plurality of layers is greater than the number of pixels of the screen corresponding to the display unit, the display unit cannot completely display each layer at the same time, that is, each layer may overlap when being displayed. For the convenience of the user, generally, the layer currently processed by the user is completely displayed on the display unit; for other layers, when an overlap with the currently processed layer occurs, the overlapped part is not displayed, i.e. is covered by the currently processed layer.
In this embodiment, by responding to the layer display position conversion operation of the user and displaying the layer corresponding to the layer display position conversion operation on the top layer, the user can conveniently obtain the display content of the layer and operate the layer.
In addition, the present invention further provides a board resource allocation device, as shown in fig. 7, the board resource allocation device includes:
