The following material is using the ARM Cortex-M0 User Guide. Minor changes have
been made regarding the specific implementation of the Cortex-M0 for the LPC122x.
The Cortex-M0 processor is an entry-level 32-bit ARM Cortex processor designed for a
broad range of embedded applications. It offers significant benefits to developers,
including:
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.
