μC/OS-II实验程序说明 软件版本:V1.0 日期:2005-05-25 多任务是指多个任务在操作系统的控制下同时运行,它的实现实际上是靠操作系统在 多个任务之间进行切换和调度。在多任务系统中,内核负责管理各个任务,即为每个任务 分配CPU时间,并且负责各任务之间的通讯。μC/OS-II操作系统最多可以支持64个任务。 每个任务的优先级不能相同,优先级数字越小,优先级越高。在μC/OS-II操作系统中, OSInit()创建了两个μC/OS-II的默认任务:一个是OS_TaskIdle,即CPU空闲任务,它拥有 最低的优先级,当有其他任务运行时此任务处于就绪态,没有其他任务时就是它在运行, 该任务是μC/OS-II必需的任务;另一个任务是OS_TaskStat,它每隔一段时间就做一些统-Arm adt IDE

    ARM Architecture Reference Manual The purpose of this manual is to describe the ARM instruction set architecture, including its high code density Thumb® subset, and three of its standard coprocessor extensions: • The standard System Control coprocessor (coprocessor 15), which is used to control memory system components such as caches, write buffers, Memory Management Units, and Protection Units. • The Vector Floating-point (VFP) architecture, which uses coprocessors 10 and 11 to supply a high-performance floating-point instruction set. • The debug architecture interface (coprocessor 14), formally added to the architecture in ARM v6 to provide software access to debug features in ARM cores, (for example, breakpoint and watchpoint control).-ARM Architecture Reference Manual The purpose of this manual is to describe the ARM instruction set architecture, including its high code density Thumb® subset, and three of its standard coprocessor
