本文按照A2800汽车发动机分析仪的高速、实时处理信息的要求,在DSP与ARM系统的硬件电路、DSP信息处理驱动软件的基础之上,以VRTX嵌入式实时多任务操作系统为核心,以ARM为开发平台,设计ARM(S3C44BOX)嵌入式应用软件系统,应用彩晶和触摸屏实现汽车数字示波器功能,实现良好的人机交互功能。本文针对高速、实时的要求,完成嵌入式应用软件系统总体设计,完成GUI界面任务设计、DSP刷波形任务设计和菜单MENU任务设计。文中描述了系统软件和三个任务软件系统的设计思想,给出了系统应用软件和各部分应用软件的程序框图。所设计的软件系统通过调试,达到高速、实时处理应用的要求。
According to the requirements of high-speed and real-time processing information of A2800 automobile engine analyzer, based on the hardware circuits of DSP and ARM system and DSP information processing and driver software, VRTX embedded real-time multitasking operating system is the core, Development platform, the design of ARM (S3C44BOX) embedded application software system, the application of color and touch-screen automotive digital oscilloscope function, to achieve good human-computer interaction. In this paper, for high-speed, real-time requirements, to complete the overall design of embedded application software system, complete GUI interface task design, DSP brush waveform task design and menu MENU task design. The paper describes the design idea of system software and three task software systems, and gives the program block diagram of system application software and each part of application software. The designed software system through debugging, to achieve high-speed, real-time processing applications.
