Embodiment Construction

[0032] In order to make the purpose, content and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0033] Technical solution of the present invention is as follows:

[0034] S1. When preparing data, write a data conversion program to convert a font file of a certain font from a text file into a hexadecimal data file, and generate a font data file and a verification data sum;

[0035] S2, use the monitoring program running on the DSP to burn, and write the font data file and the verification data into the FLASH;

[0036] S3. When the system is powered on and initialized, the DSP reads the font data file and the verification data sum stored in the FLASH, and writes the read font data file into the SDRAM memory space pointed to by the font pointer;

[0037] S4. After the system runs, the display program on the DSP rece...

Abstract

The invention relates to a display processing method based on a DSP, and belongs to the field of graphic display. During data preparation, a data conversion program is written, a font library file ofa certain font is converted into a hexadecimal data file from a text file, and a font library data file and a check data sum are generated; the DSP writes the word stock data file and the check data sum into FLASH; when the system is powered on and initialized, the DSP reads the word stock data file and the check data sum stored in the FLASH and writes the word stock data file and the check data sum into an SDRAM memory space pointed by a word stock pointer; after the system runs, a display program on the DSP receives an external drawing instruction and a control instruction in real time, calls a corresponding font library pointer according to fonts of display characters, calculates character dot matrix information, processes all picture information and then sends the processed picture information to the FPGA, and the FPGA outputs and displays the processed picture information according to an LVDS time sequence after processing the picture information. According to the invention, flexible use of multiple fonts of the system is supported, and the problem that both the operation space and the operation efficiency cannot be considered is solved.

Description

technical field [0001] The invention belongs to the field of graphic display, and in particular relates to a display processing method based on DSP, which can realize rapid display of graphic images of various fonts. Background technique [0002] Digital signal processing (DSP for short) is a technology that involves many disciplines and is widely used in many fields. With the rapid development of computer and information technology, DSP technology has emerged and developed rapidly. At present, it has been used in computers, electronics, Communication, instrumentation, military and other fields have been widely used, and the use of DSP technology in the field of graphic display has become more and more mature. In the process of realizing graphic display, character display is a very important function. Currently, there are two commonly used methods for character display: [0003] One is to compile the program and the font together, calculate the offset of the character in th...
