基于异构多核SoC的图形用户界面的构建方法

A method of building GUI based on heterogeneous multi-processor SoC

针对异构多核片上系统的FPGA原型没有可供交互的图形用户界面问题,提出一种图形用户界面的构建方法。该方法根据系统中显示控制器的工作原理和硬件特点,开发Linux操作系统内核层的Framebuffer驱动程序,借助MiniGUI的fbcon图形引擎进行MiniGUI移植,从而为系统构建了图形用户界面。测试结果表明,所构建的图形用户界面能够为系统提供良好的人机交互接口。

Due to the nonexistence of GUI （Graphical User Interlace） on the heterogeneous multi- processor SoC （System on Chip） FPGA prototype system, according to the principle and specific hardware of the display controller used in this system, a Framebuffer driver is developed in order that Mini GUI could be ported for the purpose to build GUI for this SoC. The test and interactive results show that the GUI can provide friendly interactive interface for the system.
