Web10 Oct 2012 · Interrupts are a major feature of most embedded microcontrollers and effective real time response to interrupts is vital in low power systems that often rely on a ‘run fast then stop’ approach to energy efficiency. ... Tail chaining – If another exception is pending when an Interrupt Service Routine (ISR) exits, the processor does not ... WebTail Chain Control by NVIC. Arm ® Cortex ® -M3 has become high-speed PUSH/POP processing through control of the NVIC. In addition, if the interrupt request occurs at the same time or a high-priority interrupt request occurs during interrupt processing, the automatic save of registers by PUSH/POP is omitted, and the processing timing is …
WebVideo created by Prepárate for the course "Armv8-M Architecture Fundamentals". This module is an essential foundation module for any Armv8-M Mainline implementation training course. It introduces the Exception Handling model for the Armv8-M ... Web10 Jun 2013 · Next the controller finds another interrupt is pending and starts to handle this. This second interrupt handler starts by saving the context (push registers). The effect is that in between the two interrupt handlers a restore context (pop) and save context (push) is executed. Tail chaining in hardware prevents this.
