【摘要】：设计自主知识产权的图形处理器(Graphic Processing Unit,GPU),对国家信息安全和机载图形芯片的自主保障意义重大.为满足机载应用的双路显示需求,设计并实现了支持双路显示的GPU显示控制单元.通过加入视频输入模块,使其具备视频输入功能;通过设置两条显示处理通路,使其具备双路显示功能,支持两路视频的独立、复制和拼接显示;通过在显示处理通路中加入叠加及HSV、Gamma和RGB调整模块,使其具备视频、图形及光标的叠加及多种色彩调整功能;通过集成多种类型接口,使其支持多种显示设备.构建了仿真验证平台和FPGA验证平台对显示控制单元进行验证,其结果表明,设计功能正确、性能满足要求,可用于GPU芯片设计.目前,该单元已集成到某GPU IP之中,并已完成FPGA验证.
[Abstract]:The design of graphic processor (graphic Processing Unit) with independent intellectual property rights is of great significance to national information security and the independent guarantee of airborne graphics chips.In order to meet the dual display requirements of airborne applications, a GPU display control unit supporting dual display is designed and implemented.By adding video input module, it has video input function, by setting two display processing paths, it has dual display function to support independent, duplicated and spliced display of two channels of video.By adding superposition and HSV Gamma and RGB adjustment modules into the display processing path, it has the functions of video, graphics and cursor superposition and multi-color adjustment. By integrating various types of interfaces, it can support a variety of display devices.The simulation verification platform and the FPGA verification platform are constructed to verify the display control unit. The results show that the design function is correct and the performance meets the requirements. It can be used in the design of GPU chip.At present, the unit has been integrated into a GPU IP and FPGA verification has been completed.
