Embodiment Construction

[0025] The present invention will be described in detail below according to the accompanying drawings, which is a preferred embodiment among various implementations of the present invention.

[0026] Such as figure 1 As shown, the present invention has an FPGA chip, 8 external memory SRAMs, 2 pieces of FLASH memory, and 4 parts such as an external sending chip.

[0027] Two pieces of FLASH are used to store instructions and library respectively, 8 pieces of external memory are used for graphics acceleration display operation, FPGA is used as the core of control and data processing, the sending chip is used to convert the data output by FPGA, convenient for format conversion, and the external display medium LCD displayed on the display or a normal monitor.

[0028] The entire workflow is as follows. At the beginning of power-on, the Microblaze soft-core processor inside the FPGA imports the instruction data in the external instruction FLASH into the internal RAM of the FPGA, a...

Abstract

The invention relates to a graph generator based on an FPAG (Field-Programmable Gate Array) and a working method thereof. The graph generator comprises an FPGA chip, multiple external SRAMs (Static Random Access Memories), FLASH memories and an outgoing sensing chip, wherein the FPGA chip is respectively in control connection with the eight external SRAMs; two FLASH memories and the outgoing sending chip are used for controlling and processing data; the number of the FLASH memories is two, comprising a graph gallery FLASH chip and a command FLASH chip respectively used for storing commands and the graph galleries; the multiple external SRAMs are used for accelerating the display of the graphs; and the outgoing sensing chip is used for converting the format of the data output from the FPAG.

Description

technical field [0001] The present invention relates to the technical field of graphic generation, and more specifically relates to a graphic generator based on FPGA (Field-Programmable Gate Array) and its working method. Background technique [0002] In the airborne electronic integrated display system, the aircraft parameters transmitted to the pilot are more and more dependent on the graphic display, because the graphic display can provide the pilot with comprehensive information, which is conducive to the pilot to quickly and qualitatively grasp the whole situation, especially for fighter pilots. of significance. As a graphics display core graphics generator is good or bad, it is directly related to the performance of the graphics display system. [0003] In the existing graphics generation method, there are mainly two forms: a kind of graphics generation method is to generate with pure hardware, and the character graphics are all produced by fitting straight line segme...
