摘要
在多媒体应用开发平台OMAP5910上构建了一种新型的三维显示系统,在此系统上移植源码公开的、可移植、可裁剪的占先式的实时多任务操作系统μC/OS-Ⅱ,运用BootLoader功能实现目标系统的脱机运行。着重给出了FLASH、SDRAM的硬件设计以及操作系统的启动加载程序BootLoader的设计方法,同时系统中程序代码存放在外设FLASH,利用SDRAM来运行用户程序,加快了系统的运行效率。
A new system of 3D display is designed based on OMAP5910,the multimedia application development platform.In this system,the multitask OSμC/OS-Ⅱin characteristic of a fully- preemptive,real-time,portable and scalable kernel is transplanted,andμC/OS-Ⅱis applicable to embedded system,implementing offline system by Boot Loader.In this paper,the hardware design of FLASH and SDRAM is given,and the design method of the Boot Loader of OS is also presented.In this system,FLASH stores program codes,and SDRAM runs program in order to improve the operation speed.
