IPC@CHIP Documentation - SC12 @CHIP-RTOS V1.10

RTOS task switch time
Performance comparision between IPC@CHIP family
The following diagramm and C code shows how the measured values were calculated.
void huge taskA(void)
{
RTX_Sleep_Request();
}
void huge taskB(void)
{
RTX_Restart_Task (taskAID);
RTX_Wakeup (taskAID);
}
void main (void)
{
//...
result = RTX_Create_Task_Without_Run(&taskAID , &taskAdefblock);
RTX_Sleep_Time(10);
result = RTX_Create_Task(&taskBID , &taskBdefblock);
//...
}

Interrupt latency
The interrupt handler latency is the time from the processor's first response to an interrupt request signal through to the first
useful instruction inside of the user interrupt service procedure.
The user interrupt service procedure can be of type HW API or RTX.
