摘　　要：低功耗、国产化和高安全是现代军用车载座舱设计的发展趋势,利用低功耗、高性能的图形处理芯片是实现这一设计的有效途径。分析典型环境下车载座舱设计的基本需求,针对传统车载座舱的信息获取效率低、座舱布局杂乱、仪表信息独立等缺点,给出基于国产图形处理器的车载显示系统设计方案。CPU通过接收外围传感器数据生成绘图信息,通过与GPU进行握手通信发送绘图指令,基于GPU的多核心并行计算的优势快速生成显示界面。测试结果表明,该方案开发的座舱显示界面画面清晰、流畅,能够替换国外产品。Low power consumption,localization and high safety are the development trend of modern military vehicle cabin design.The use of low power consumption and high performance graphics processing chip is an effective way to achieve this design.Based on the analysis of the basic requirements of on-board cockpit design in typical environment,aiming at the disadvantages of traditional on-board cockpit,such as low information acquisition efficiency,disorderly cockpit layout and independent instrument information,the design scheme of on-board display system based on domestic graphics processor is presented.The hardware platform and vehicle display interface are designed with this scheme.The test results show that the cockpit display interface developed by the scheme is clear and smooth,and can achieve the purpose of replacing foreign products.
