[ARM-PowerPC-ColdFire-MIPS] mmuos DL : 1: 这是一个不到2000行的操作系统，巧妙地利用ARM9 CPU的内存管理单元(MMU)实现进程的切换。ARM9的4G虚拟地址可分成128个进程空间，每个32M。虽然它们的虚拟地址(VA)都是0-(32M-1)，但是对应的MVA(Modified vitual address,由虚拟地址VA和进程号PID组合而来)不一样，设置MVA对应的页表指向不同物理地址就可以很方便地让各进程运行空间相互隔开。代码很少，注释丰富，希望能对想理解操作系统、了解ARM体系结构的朋友有所帮助。 -This is a trip of less than 2000 operating system, cleverly using ARM9 CPU memory management unit (MMU) to achieve the switching process. ARM9 4G virtual address can be divided into 128 process space, each 32M. While their virtual address (VA) are 0- (32M-1), but the corresponding MVA (Modified Virtual address, and by the virtual address VA and the process of portfolio from PID) not the same, set MVA corresponding page table at the different physical address can be very easy to let the the process of separating the mutual operation of space. Code rarely Notes rich, in hopes of understanding the operating system, understanding the ARM architecture friends help.

[ARM-PowerPC-ColdFire-MIPS] ruanjiandingshiqi DL : 0: 本软定时器模快所通过一个唯一的索引（即序号）来表识每一个软定时器，这个序号从0到MAX_SOFT_TIMER-1 ，最多为255个。要使用软定时器模块，首先需要让软定时器管理任务运行起来。软定时器管理任务的函数名称为SoftTimer，所以只需要Small RTOS的要求在Config.h的数组TaskFuction加上SoftTimer项即可。因为软定时器执行的任务时间等因素不确定，所以一般把这个任务优先级定得比较低。-the soft-timer module adopted by only one index (ie serial numbers) to form a soft know each timer, the serial number from 0 to MAX_SOFT_TIMER-1, a maximum of 255. To use soft timer module, the first need for the soft-timer management tasks running up. Soft-timer management tasks for the function name SoftTimer. So Small RTOS only at the request of an array TaskFuction Config.h SoftTimer items can be added. Soft-timer because the task uncertain factors such as time, in general the priority tasks set aside a lower level.
