1、REALTIME_PRIORITY_CLASS:Real-time,实时优先级类 2、HIGH_PRIORITY_CLASS:High,高优先级类 3、ABOVE_NORMAL_PRIORITY_CLASS:Above normal,高于标准 4、NORMAL_PRIORITY_CLASS:Normal,标准 5、BELOW_NORMAL_PRIORITY_CLASS:Below normal:低于标准 6、IDLE_PRIORITY_CLASS:Idle,空闲 你也可以更改一个特定的进程优先...
real-time REALTIME_PRIORITY_CLASS high HIGH_PRIORITY_CLASS above normal ABOVE_NORMAL_PRIORITY_CLASS normal NORMAL_PRIORITY_CLASS below_normal BELOW_NORMAL_PRIORITY_CLASS idle IDLE_PRIORITY_CLASS 进程运行后可以调用SetPrioritClass来改变进程优先级类。 BOOLSetPriorityClass( HANDLE hProcess, DWORD fdwPriority)...
这导致如果你把此进程的优先级设置成 HIGH_PRIORITY_CLASS 或者 REALTIME_PRIORITY_CLASS 就会导致系统一些进程出问题。 Windows自带的多媒体计时器 以5ms为一个周期 #include"HAL.h" #include<Windows.h> #pragma comment(lib,"Winmm.lib") using namespace std; HANDLE trig = CreateEventW(NULL, 0, 0, NUL...

Mapped to non-real-time priorities. The following table shows the default priority levels that are associated with device drivers. You can override these values by changing the source code for the drivers or by setting values in the registry. The registry paths in the table assume that the roo...
Proper tuning of ISTs can have a large impact on the overall performance of any real time system. Put more processing into the ISR. This is discouraged because when an ISR is running, no other threads are scheduled, and lower priority interrupts are masked. You might experience poor device ...

你可以更改它的线程相对优先级,Thread中的Priority属性,向它传递ThreadPriority枚举类型中定义的5各值之一,即在上表中的灰色部分列。 Windows为自己保留了优先级0和Realtime范围,CLR为自己保留了Idle 和Time-Critical优先级。 CLR的终结器线程以Time-Critical优先级运行。开发人员不用用到这些优先级,但了解一下还是不...
