ARM Cortex-M0 is the development of a company to provide ultra-low-power, low-cost microprocessors, using a unique interrupt control system that can effectively accelerate the process interrupt response. By M0 processor's interrupt control system can be more in-depth understanding of microprocessor architecture and interrupt control system design.This paper outlines the structure of the embedded system, status quo and development trends, then explained the priority of interrupts and interrupt nesting concept, focusing on the ARM Cortex-M0 structural characteristics, summarized M0 exception and interrupt characteristics, and the interrupt priority for M0, nested Vectored Interrupt controller (NVIC) and the ARM Cortex microcontroller Software Interface Standard (CMSIS) for illustration, the last in ALTERA DE2-115 with the keypad on edge-triggered interrupts, by observing the status LED flashing to verify that implements interrupt control.Keywords: AR...
