RTOS should use  i/o sample  clock(counter of sample cycle)  instead  of  the realtime clock(32.768khz)

MCU (mpc8247)   can  avoid  the  realtime clock interupt  when  mcu  is  busy.  so   MCU peak  of calculation   is   isochronous   with  I/O device  sample  and transmit cycle.     use  a  programmable-counter  of    sample  and transmit cycle  . In C language ,  the function delay  of  time (ms)(for example  timer, delay,sleep) can  be  realized  with  no- MCU- interupted  mode,because when the timer  is arrived ,the programm  can guarantee  the cpu is free,   . reduce  the operation of (push  pull  with stack&heap)...so  system   will be  faster
