arm10-behavioral的行为仿真代码ｖｅｒｉｌｏｇＨＤＬ-arm10-behavioral simulation code of conduct verilogHDL

基于STR710和嵌入式操作系统的串口驱动程序-STR710-based and embedded operating systems serial driver

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.

这是费浙平写的《ARM 体系结构及基于ARM 的嵌入式开发》非常不错。-Zhejiang-written "ARM Architecture and ARM-based embedded development" very good.

就像在嵌入系统中使用C语言替代汇编一样,在嵌入系统中使用RTOS是大势所趋。原因主要是现在在大多数情况下编程效率比执行效率重要（单片机便宜嘛）。-As in embedded systems using C language as an alternative assembly, the use of RTOS in the embedded systems is a general trend. The main reason is now in most cases more efficient than the implementation of the efficiency of programming important (SCM cheap Well).
