原创 ARM_00_OSV1.1版(ADuC702x版)

将时间片处理改到了IRQ中,并增加了串口发送中断驱动,串口发送时只占用很少的CPU资源。可以根据需要，仿照串口发送中断进行驱动编程.

 

 

以下是使用串口中断驱动CPU使用情况，

TaskName              PID  CPU   CPUTime    MemoryUsed   Status
---------------------------------------------------------------
Task5               68716    0% 00:01:18         256 B  Ready 
SystemIdle          67160   98% 05:35:43           0 B  Ready 
Task3               68204    0% 00:00:06         256 B  Delay 
Task4               68460    0% 00:00:03         256 B  Delay 
Task2               69228    0% 00:01:07         256 B  Suspend
Printer Driver      67436    0% 00:00:10         512 B  Suspend
Task1               68972    0% 00:01:18         256 B  Suspend
Task Manager        67948    1% 00:02:46         304 B  Running

 

以下是不使用串口中断驱动时CPU的使用情况:
