28.3.1 System-level interface
28.3.2 Integrated configurable debug
28.3.3 Cortex-M0 processor features summary
The Cortex-M0 processor is built on a highly area and power optimized 32-bit processor
core, with a 3-stage pipeline von Neumann architecture. The processor delivers
exceptional energy efficiency through a small but powerful instruction set and extensively
optimized design, providing high-end processing hardware including a single-cycle
multiplier.
The Cortex-M0 processor implements the ARMv6-M architecture, which is based on the
16-bit Thumb instruction set and includes Thumb-2 technology. This provides the
exceptional performance expected of a modern 32-bit architecture, with a higher code
density than other 8-bit and 16-bit microcontrollers.
The Cortex-M0 processor closely integrates a configurable Nested Vectored Interrupt
Controller (NVIC), to deliver industry-leading interrupt performance. The NVIC:
The tight integration of the processor core and NVIC provides fast execution of interrupt
service routines (ISRs), dramatically reducing the interrupt latency. This is achieved
through the hardware stacking of registers, and the ability to abandon and restart
load-multiple and store-multiple operations. Interrupt handlers do not require any
assembler wrapper code, removing any code overhead from the ISRs. Tail-chaining
optimization also significantly reduces the overhead when switching from one ISR to
another.
To optimize low-power designs, the NVIC integrates with the sleep modes, that include a
Deep-sleep function that enables the entire device to be rapidly powered down.
The Cortex-M0 processor provides a single system-level interface using AMBA
technology to provide high speed, low latency memory accesses.
The Cortex-M0 processor implements a complete hardware debug solution, with
extensive hardware breakpoint and watchpoint options. This provides high system
visibility of the processor, memory and peripherals through a 2-pin Serial Wire Debug
(SWD) port that is ideal for microcontrollers and other small package devices.
