[0107] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0108] refer to Figure 1 , Figure 1 Schematic diagram of the structure of a baseboard management controller information display system proposed in an embodiment of the present application. The system is integrated into a baseboard management controller, such as Figure 1 As shown, the system includes:

[0109] A text display memory is used to store text information of a baseboard management controller that needs to be displayed; a character library is used to store pixel values ​​corresponding to characters; a display memory is used to store pixel value data corresponding to the text information; a display timing generation module is used to generate a timing signal, drive an external display, and display the baseboard management controller information according to the pixel value data, and the display timing generation module is connected to the display memory; a data conversion and processing module is used to search for the corresponding pixel value data in the character library according to the text information in the text display memory, and send the pixel value data to the display memory. The data conversion and processing module determines whether the position corresponding to the character to be displayed is in a highlighted area; if the position corresponding to the character is in a highlighted area, the position corresponding to the character is set to a highlighted state. The text display memory includes: a fixed screen text display memory, which is used to store the text information displayed in a fixed position area of ​​a display device; and a scrolling screen text display memory, which is used to store the text information displayed in a scrolling display area of ​​the display device.

[0110] In this embodiment, the baseboard management controller (BMC) is a special controller for monitoring and managing the server. It is not available in ordinary computers, but it is a must-have for server products. Compared with ordinary computers, servers have higher and more stringent requirements in terms of stability, reliability, security, performance, manageability, etc. At this time, BMC is needed to control the server. In order to maintain and manage the server, the operation and maintenance personnel use the relevant information provided by the BMC to understand the current operating status, error exceptions, and historical operation records of the server, including equipment information management: recording the server model, manufacturer, date, production and technical information of each component, chassis information, motherboard information, etc., BMC information; server status monitoring management: detecting the temperature, voltage and other health status of each component of the server (CPU, memory, hard disk, fan, frame, etc.); remote control management of the server: server power on / off, restart, maintenance, firmware update, system installation, etc.; maintenance management: log management, user management, basic input and output system management, alarm management, etc.

[0111] In this embodiment, the display timing generation module is used to generate standard VESA (Video Electronics Standards Association, a video display standard) timing signals, including vsync, hsync signals, data signals (R, G and B data), and data valid signals, so as to drive the display of the external display. The RGB color mode is a color standard in the industry. It is obtained by changing the three color channels of red (R), green (G), and blue (B) and superimposing them on each other to obtain various colors. RGB represents the colors of the three channels of red, green, and blue. This standard almost includes all colors that can be perceived by human vision and is one of the most widely used color systems. The display data (RGB) is obtained from the video memory, which stores a frame of data. The display timing generation module reads data from the video memory in sequence according to the timing of vsync and hsync for display. The display frequency is 60Hz, that is, the data in the video memory 1 is repeatedly read 60 times in 1 second. The resolution of the display device is 1024x768, and each pixel is represented by 32 bits in the ARGB format, where 31:24 bits represent A, which has no practical meaning; 23:16 bits represent R data; 15:8 bits represent G data; and 7:0 bits represent B data.

[0112] The text data of the baseboard management controller information currently to be displayed is stored in the text display memory, which is stored in the form of ASCII code, using 8 bits to represent one character, and a total of 256 characters can be displayed. In this embodiment, a 1024x768 resolution is used for display, and the positive screen can display 128x48 characters, that is, each character occupies 16x8 pixels, and the entire screen can display 48 lines of characters, and each line can display 128 characters.

[0113] The font module stores 256 characters in pixel format. Each character is identified by 16x8 bits. Figure 2 , Figure 2 is a schematic diagram of a display effect proposed in an embodiment of the present application, such as Figure 2 As shown in the figure, 0 represents the background color white, and 1 represents the foreground color black, so the character A is displayed. The font library uses a total of 256x16x8bit space.

[0114] In this embodiment, the data conversion and processing module reads the first byte byte from the text display memory. Byte is a unit of measurement used to describe storage capacity and transmission capacity in computer information, and is the basic storage unit of the computer. A byte consists of 8 adjacent binary bits, each of which consists of 0 or 1. A byte is the smallest operable storage unit in computer technology. The value of the byte is used as an index value to read 16x8bit data from the font library, that is, the data of a character, and then the read data is parsed in sequence. If the data is bit0, 32bit RGB data (32`hFF000000) is written to the corresponding position in the display memory to represent the white pixel value. If the read data is bit1, 32bit RGB data (32`hFFFFFFFF) is written to the corresponding position in the display memory to represent the black pixel value. This pixel value can also be changed. For example, bit0 corresponds to black pixel value, and bit1 corresponds to white pixel value. It is specifically determined according to the background color and foreground color of the display scene. If the background color is white and the foreground color is black, 0 can be used to represent white and 1 to represent black. If the background color is black and the foreground color is white, 1 can be used to represent white and 0 to represent black. You just need to swap them when filling in the pixel values.

[0115] The font library can be stored in RAM (Random Access Memory), also called main memory, which is an internal memory that directly exchanges data with the CPU. It can be read and written at any time (except when refreshed), and the speed is very fast. It is usually used as a temporary data storage medium for operating systems or other running programs. When working, RAM can write (store) or read (remove) information from any specified address at any time. The biggest difference between it and ROM is the volatility of data, that is, once the power is off, the stored data will be lost. RAM is used in computers and digital systems to temporarily store programs, data and intermediate results. The size of the RAM is 256x128, each row represents a character, and the characters are stored in the order represented by the ASCII code. In the computer, all data must be represented by binary numbers when stored and calculated (because the computer uses high and low levels to represent 1 and 0 respectively). For example, 52 letters such as a, b, c, d (including uppercase) and numbers such as 0 and 1, as well as some commonly used symbols (such as *, #, @, etc.) must also be represented by binary numbers when stored in the computer. As for which binary numbers represent which symbols, of course everyone can agree on their own set (this is called encoding), and if everyone wants to communicate with each other without causing confusion, then everyone must use the same encoding rules, so the relevant standardization organization has introduced the ASCII encoding, which uniformly stipulates which binary numbers are used to represent the above-mentioned commonly used symbols. It is convenient and easy to use, and it is a standard regulation that is easy to query. If you access the RAM, you can directly access it as an address.

[0116] refer to Figure 3 , Figure 3 : is a schematic diagram of the corresponding relationship of pixel value writing proposed in an embodiment of the present application, such as Figure 3 As shown in the figure, the corresponding relationship of the pixel value written into the display memory is: the first 8 pixels are written into the first 8 positions of the first row, the next 8 pixels are written into the first 8 positions of the second row, and so on. According to the sequential data read from the text display memory, each character is given a number, that is, (X, Y), where X represents the number of rows and Y represents the number of columns. The pixel value of the character read out is n bits in the character library, and the corresponding conversion relationship is:

[0117] The pixel value data represented by the 0th bit in the text display memory is written to the position in the display memory 1: 4*1024*(X-1)+4*8*(Y-1)+0;

[0118] The pixel value data represented by the first bit in the text display memory is written in the position of display memory 1: 4*1024*(X-1)+4*8*(Y-1)+4;

[0119] …

[0120] The pixel value data represented by the 7th bit in the text display memory is written in the display memory 1 at the position: 4*1024*(X-1)+4*8*(Y-1)+28;

[0121] The pixel value data represented by the 8th bit in the text display memory is written in the display memory 1 at the position: 4*1024*(X)+4*8*(Y-1)+0;

[0122] The pixel value data represented by the 9th bit in the text display memory is written in the position of display memory 1: 4*1024*(X)+4*8*(Y-1)+4;

[0123] …

[0124] The pixel value data represented by the 15th bit in the text display memory is written in the display memory 1 at the position: 4*1024*(X)+4*8*(Y-1)+28;

[0125] The pixel value data represented by the 16th bit in the text display memory is written in the display memory 1 at the position: 4*1024*(X+1)+4*8*(Y-1)+0;

[0126] …

[0127] The pixel value data represented by the 255th bit in the text memory is written to the position in the video memory 1: 4*1024*(X+15)+4*8*(Y-1)+28. And so on.

[0128] The display software of the baseboard management controller sets the highlighted display area, and generates a highlighted area of ​​[X,Y][X+W,Y][X,Y+H][X+W,Y+H] for the starting coordinate position (X,Y) of the characters to be highlighted on the entire screen and the size of the highlighted area (H,W). The data conversion and processing module determines whether the position of the character to be displayed exists in the highlighted area. If so, the background color and the foreground color are reversed, that is, 0 represents the foreground color and 1 represents the background color, and the pixel value is converted.

[0129] If it is a scrolling display, you need to scroll the display area to display the text. The starting position of the display is initialized to 0. The up and down keys input on the keyboard determine whether the starting position of the display is plus 1 or minus 1, so as to realize the scrolling of the screen. When the starting position of the display is located at the last position in the area that is less than one screen, the text display memory content is copied to the starting position for display.

[0130] refer to Figure 4 , Figure 4This is a screen display diagram proposed in an embodiment of the present application. In the figure, starting from the text display starting position, it includes screen display area 0 to screen display area 7, with a total of 8 display areas. The number of display areas can also be set according to actual conditions.
