IRQ for the ARM Embedded System of interrupt handling procedures

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).
