The present invention relates to an electronic device, and more particularly to an electronic device in which the presentation of the boot animation is not performed by the processor during the booting process.

At present, in the process of starting the general electronic device, the central processing unit (CPU) displays a boot animation on the display in addition to executing multiple booting programs. In addition to telling the user that the boot is currently in progress, the boot animation can also add interest when the electronic device is turned on. However, while the central processor is executing one or more booting programs, if the display of the boot animation is to be driven, the speed of booting the electronic device is inevitably slowed down.

In order to understand the technical characteristics, content and advantages of the creation and the effects that can be achieved by the examiner, the author will use the drawings in detail and explain the following in the form of the examples, and the drawings used therein The subject matter is only for the purpose of illustration and supplementary manual. It is not necessarily the true proportion and precise configuration after the implementation of the original creation. Therefore, the proportion and configuration relationship of the attached drawings should not be limited to the scope of patents created in actual implementation. Narration.

The embodiments of the electronic device according to the present invention will be described with reference to the related drawings. For the sake of understanding, the same components in the following embodiments are denoted by the same reference numerals.

FIG. 1 is a schematic diagram of an electronic device according to an embodiment of the present invention. As shown, the electronic device 10 includes a memory 100, a storage module 110, a single core processor 120, a display engine 130, and a display 140. The memory 100 includes a first buffer 101 and a second buffer 102. The storage module 110 stores a first image 111 and a second image 112. The single core processor 120 is electrically coupled to the storage module 110, and the single core processor 120 extracts the first image 111 to the first buffer 101 and the second image 112 to the second buffer 102. The display engine 130 is electrically coupled to the memory 100. During the startup of the electronic device 10, the display engine 130 can output image data according to the first image 111 and the second image 112. The display 140 is electrically coupled to the display engine 130, and the display 140 can display an animated image according to the image data independently of the single core processor 120. That is to say, during the power-on of the electronic device 10 of the embodiment, the display of the animated image is mainly performed by the display engine 130, and the single-core processor 120 is not responsible for processing the animated image. Therefore, the single-core processor 120 of the electronic device 10 of the present embodiment can be used to perform other one or more booting procedures completely during booting, without being affected by the booting animation, so the booting speed of the electronic device of the embodiment Can be shortened.

Further, the display engine 130 stores an Alpha Blending Setting (α Blending Setting) 131, and the display engine 130 can change the transparency of the first image 111 and the second image 112 according to the alpha blending setting 131, and superimpose and overlap. The first image 111 and the second image 112 form an animated image. In other words, the animated image may be a superposition of the first image 111 and the second image 112 under the gradient transparency.

Specifically, the alpha blending setting 131 can have a plurality of transparency level information, and the display engine 130 can adjust the transparency of the first image 111 and the second image 112 according to the plurality of transparency level information. For example, if each pixel uses a bitmap stored in 32 bits, the alpha blending setting 131 can have 256 levels of transparency information. That is to say, the first image 111 and the second image 112 can be separated from 256 kinds of transparency effects from completely transparent to translucent to completely opaque.

Further, the alpha blending setting 131 also has time interval information in which the transparency of the first image 111 and the second image 112 is changed. For example, the alpha blending setting 131 can set the time interval information to be 1/60 second. That is, the first image 111 and/or the second image 112 change the transparency once every 1/60 second, wherein it is possible that the first image 111 becomes more transparent and the second image 112 becomes more opaque. . In this way, the display engine 130 can drive the display 140 to display the animated image through the time interval information and the transparency level information.

In the above embodiment, the first buffer 101 may be a Video Frame Buffer, and the second buffer 102 may be an On-Screen-Display Buffer (OSD Buffer), but this creation Not limited to this. In addition, the memory 100 can be a volatile memory such as a Dynamic Random Access Memory (DRAM). The storage module 110 can be a non-volatile memory such as a NAND gate flash memory.

Next, the operation steps of the boot animation of the electronic device of the present invention will be further disclosed, please refer to FIG. 2 . The step of starting the animation of the electronic device comprises the step 200: starting, that is, when the electronic device 10 is connected to the power and turned on. Then, step 210 is performed: executing the boot load code, for example, loading the boot-related program code from the storage module 110, including loading the first image 111 and the second image 112 from the storage module 110 to the memory. The first buffer 101 of 100 is in the second buffer 102. Next, proceed to step 220: initialize two original images. That is, the first image 111 and the second image 112 are initialized, and the alpha blending setting 131 is set, for example, setting time interval information and setting how many transparency levels are from full transparency to full opacity.

Next, proceed to step 230: drive the boot animation. At this time, the single core processor 120 can process the other one or more booting programs, and the booting programs are zero-related to the animated images required for booting. That is to say, at this time, the animation image is completely responsible for the display engine 130, and the single-core processor 120 can completely handle other work required for booting, thereby shortening the boot time.

Then, step 240 is performed, and the other programs are directly continued without waiting for the boot animation to end. That is to say, after the single core processor 120 of the electronic device 10 executes the booting process, the booting period is substantially ended at this time, but the display engine 130 can continue to display the booting animation. At this time, the single core processor 120 can directly control the display 140 to display the main screen without waiting for the boot animation to end, to remind the user that the operation of the electronic device 10 can be started.

In summary, according to one or more embodiments of the present invention, during operation of the electronic device, the single-core processor does not need to perform the display of the boot animation, but can be completely responsible for the display engine, so the single-core processor can Completely process other booting programs to shorten the boot time of the electronic device.

The above is intended to be illustrative only and not limiting. Any equivalent modifications or alterations to the spirit and scope of this creation shall be included in the scope of the appended patent application.
