[AUTOSAR nine c/s principle Architecture]

---

1 A synchronous invocation

• A synchronous invocation Server Yes, you can set the time limit （Timeout） Of , once Beyond the time limit Return（timeout）.
• Synchronization is in Rte_Call Start timing when you're ready

---

2 Asynchronous call

2.1 With time limits Timeout

• The time limit of asynchronous call is different from that of synchronous call , Synchronization is in Rte_Call Start timing when you're ready , Asynchronous is in RequestResult Start timing when you're ready .

2.2 Loop waiting for Polling

• Ask for the result every once in a while , If not, continue to execute the following code , Until the next interval to ask again , Finally, until the result is obtained .

2.3 Trigger Trigger

• The way of triggering is a bit like ADC interrupt , once ADC The completion of the conversion will produce an interrupt , In the interrupt ADC Do some preliminary processing of the data .
• once Server After execution , It triggers a callback Runnable2 Function execution , take Server The data of Return To this Runnable2 Do some preliminary treatment （ For example, put it into a global variable for other code to use ）
