[0019] The present application is described more fully below with reference to the accompanying drawings which illustrate illustrative embodiments of the present application. However, the present application may be implemented in different forms and should not be interpreted as being limited to the embodiments given herein. The following embodiments are given to make the disclosure herein comprehensive and complete, so as to more fully convey the scope of protection of the present application to those skilled in the art.

[0020] In this specification, terms such as "comprise" and "include" indicate that in addition to the units and steps directly and explicitly stated in the specification and claims, the technical solution of the present application does not exclude the situation where there are other units and steps that are not directly or explicitly stated.

[0021] Unless otherwise specified, terms such as "first" and "second" do not indicate the order of the units in terms of time, space, size, etc., but are merely used to distinguish the units.

[0022] In this specification, "display interface" refers to the viewable area displayed on a display, and the display may include but is not limited to a liquid crystal display (LCD), a liquid crystal on silicon (LCOS) display, an organic light-emitting diode (OLED) display, a digital light processing (DLP) display or a micro-electro-mechanical systems (MEMS) display, and a user can control the displayed objects (such as images, videos, texts, visual data, etc.) in the viewable interface, such as switching from a dynamic picture to a static picture.

[0023] In this specification, "dynamic display" and "static display" refer to displaying an object on a display interface using a continuously changing picture and a static picture, respectively. The dynamic display may include the scrolling display of multiple images, the playback of a video, the real-time change of visual data, etc. The static display may include the display of one or more images, the paused display of one or more frames in a video and the visual data, etc.

[0024] Figure 1 An input-output model 100 of multiple buffers according to one or more embodiments of the present application is shown.

[0025] like Figure 1 As shown in FIG. 1 , the input-output model 100 may include a first buffer 110 , a second buffer 120 , and may also include a third buffer 130 . Figure 1 The arrow in represents one direction in which the message is transmitted between these buffers. The first buffer 110, the second buffer 120 and the third buffer 130 may be integrated into one RAM memory or distributed in multiple RAM memories. The capacity of the first buffer 110 may be greater than the capacity of the second buffer 120.

[0026] Messages used for display (e.g., dynamic display or static display) may be cached in the first buffer 110, and as an alternative, the first buffer 110 may obtain the messages cached therein from the third buffer 130, and the capacity of the third buffer 130 may be equal to or greater than the capacity of the first buffer 110. Next, the cached messages may be cached from the first buffer 110 to the second buffer 120. When displaying, the cached messages may be obtained from the first buffer 110 or the second buffer 120 for display.

[0027] Figure 2 is a flowchart of a method for displaying using multiple buffers according to one or more embodiments of the present application.

[0028] exist Figure 2In step 210 of the method 200 shown in , a set of one or more messages (hereinafter referred to as a first message set) from a data source (e.g., a database stored in a memory such as a ROM, EPROM, or E2PROM) may be cached in a first buffer, and the first message set may include messages for recording images, texts, visual data, audio and video, etc. Next, one or more messages (e.g., all messages) in the cached first message set may be obtained from the first buffer for display on a display interface, such as for decoding by a video codec protocol, etc. In step 220, part of the messages in the first message set cached in the first buffer may be cached from the first buffer to a second buffer. Next, one or more messages in the part of the messages in the cached first message set may be obtained from the second buffer for display on a display interface.

[0029] In one or more embodiments, when performing dynamic display on the display interface, some messages in the cached first message set can be obtained from the second buffer (for example, all messages in the said part of messages), and when performing static display, one or more messages in the cached first message set can be obtained from the first buffer, for example, all messages in the first message set. In this way, when performing dynamic display, by reducing the amount of messages to be displayed, the occupation of computing resources (for example, computer memory) used for dynamic display can be reduced, and the jamming of dynamic pictures can be avoided or at least alleviated; on the other hand, when performing dynamic display, since each frame of the picture may usually have only a small change with the previous frame of the picture (the change is presented by the message used for dynamic display), the richness of the picture will not be significantly reduced due to the reduction of the amount of messages compared with the static display. Compared with the dynamic display of the picture that changes continuously over a period of time, the static display occupies less computing resources, so the richness of the picture can be increased by, for example, using all the messages in the first message set.

[0030] In one or more embodiments, a second message set (for example, which may come from the above data source or another data source) may be cached in a third buffer, and the second message set may also include messages for recording images, text, visual data, audio and video, etc. One or more messages (for example, all messages) in the second message set cached in the third buffer may be cached in the first buffer. A selection may be made between the first message set and the second message set already stored in the third buffer. Specifically, one of them may be selected to be cached in the first buffer based on the time expected to be spent in the process from caching the message into the buffer to displaying it on the display interface. Since the data transmission speed between buffers is faster than the transmission speed between, for example, a ROM memory and a buffer, it is expected that the time spent using the second message set already stored in the third buffer to cache it in the first buffer is shorter.

[0031] In one or more embodiments, a switch may be made between a first message set and a second message set for caching in a first buffer. When switching between a first message set and a second message set, the first buffer that has already cached the first message set may be cleared and the second message set may be cached in the first buffer, and correspondingly, the first buffer that has already cached the second message set may be cleared and the first message set may be cached in the first buffer. For example, when performing a static display, the first message set cached in the first buffer may be cleared and switched to the second message set for caching. Since the data transmission speed between buffers is faster than the transmission speed between, for example, a ROM memory and a buffer, the improved data transmission efficiency helps alleviate the jamming of, for example, dynamic images during switching.

[0032] In one or more embodiments, the same or different messages may exist in the first message set and the second message set. Since the first message set and the second message set may come from the same data source, there may be one or more identical messages or no identical messages in the first message set and the second message set. Further, the second message set may, for example, include the original data in the data source, and the first message set may, for example, include the original data in the data source and filtered data, such as data filtered by using Pandas.

[0033] In one or more embodiments, each message in the first message set may be cached in a first-in-first-out message queue formed in the first buffer according to the first-in-first-out (FIFO) rule. Similarly, each message in the second message set may be cached in a first-in-first-out message queue formed in the third buffer according to the first-in-first-out rule. Similarly, each message in the messages cached in the second buffer may be cached in a first-in-first-out message queue formed in the second buffer according to the first-in-first-out rule. The messages forming the second message set may be messages from the head position to the i-th position of the first-in-first-out queue formed by the first message set arranged in the first buffer, where i is a positive integer greater than 1 and less than n, and n is the total number of messages in the first-in-first-out queue formed by the first message set in the first buffer. For example, the second message set is formed by messages from the head position to the 5000th position of the first-in-first-out queue formed by the first message set, so that the second message set consists of 5000 messages.

[0034] In one or more embodiments, one or more of the first buffer, the second buffer, and the third buffer may be (e.g., may include) a ring buffer. Through the ring buffer, for example, computer memory may be efficiently utilized, and high read and write efficiency may be achieved because there is no need to frequently move the pointer.

[0035] Figure 3 is a schematic block diagram of a computer system. Figure 3 As shown, the computer system 300 includes at least one memory 310 (e.g., a non-volatile memory such as a flash memory, a ROM, a hard disk drive, a magnetic disk, an optical disk, etc.), at least one processor 320, and a computer program 330.
