ARM worst-case latency to respond to interrupt is 27 cycles: 2 cycles to synchronize external request. …
WebInterrupt-Driven I/O In order to allow the CPU to do other tasks while I/O operations are running, it is necessary to use interrupts. When I/O is done in this manner, the CPU programs the control registers of an I/O device, calls the scheduler, and then runs a different process until the I/O device indicates that it is done. WebThe time interval between the time the interrupt occurs and the time when ISR execution starts is called interrupt latency. Almost all computing today is interrupt-driven, which …

WebJan 29, 2024 · Serial receive is typically interrupt-driven to put characters into a buffer however Serial transmit usually polls to dump the characters into the tx register of the USART hardware which handles the output autonomously. Interrupts within interrupts is actually fairly common in real-time systems.
