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.

应用背景本代码可以用于嵌入式图形界面设计、工业控制等。用户可以将其修改或者自行设计将其投入到自己的应用中。（压缩包中附带硬件资料，用户可以参考）关键技术本测试代码采用了正点原子的4.3寸电容屏，本人将其原先的查询方式获取电容屏的改为中断方式获取用户输入，查询的效率不仅低，而且占用CPU的资源，所以本人通过查询数据手册，将其修改为中断方式获取屏幕坐标。并在此基础上移植了STemwin嵌入式GUI，用户可以将其修改或者自行设计将其投入到自己的应用中。（压缩包中附带硬件资料，用户可以参考）

/*PWMSine.c 此程序说明了如何使用 PWM 通道 4 上 要输出正弦波 PWM 通道上的单个边缘模式。PCLK 设置为 15 兆赫和有没有 prescaling 这样 PWM 时钟 是 15 mhz。基准利率是设置为 100 H 这是 256 基 10 所以基地的 PWM 频率是在 15 MHz/256 = 58.95375 千赫。 */
