The interrupt latency of the Cortex-M series processor is quite low and is deterministic. For example, the Cortex-M3 and Cortex-M4 processors have an interrupt latency of only 12 clock cycles. This latency includes time required to push a number of registers to the stack, which allows an ISR to be written as a normal C function, and avoid any hidden software overhead in interrupt processing.

These interrupt lines are usually routed to vendor-specific peripherals on the MCU such as Direct Memory Access (DMA) engines or General Purpose Input/Output Pins (GPIOs). All of these interrupts are configured via a peripheral known as the Nested Vectored Interrupt Controller (NVIC). The Exception Number for external interrupts starts at 16. The ARMv7-M reference manual has a good graphic which displays the Exception number mappings:

Cortex-R4/5 CPU and how interrupts are handled on Hercules based microcontrollers. For more as some Cortex-M (ARMv7-M architecture) processors do. Generally, an exception/interrupt processing system contains three components: All exceptions and interrupts in the Cortex-M4 MCU are handled by the NVIC.
