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 … WebFeb 2, 2024 · Interrupt response time: Reduced interrupt response time is a built-in feature of some Cortex-M processors, such as the “tail-chaining” feature of the Cortex-M4. Furthermore, code within the ISR may be a factor in interrupt latency; if the ISR code is not optimized, it may add additional latency by taking longer to complete.

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.

WebOct 19, 2010 · Hence, if we put our bootloader into ARM Cortex-M0, we need to find some way to chain the bootloader’s interrupt vector to user’s interrupt vector. Here’s how I did it: First of all, point all the interrupt vectors into single default handler, except for the Reset handler and MSP, which will always point to bootloader’s Reset handler and MSP.
