ARM Cortex-M3/M4 Software Design

Standard Level - 3 days

view dates and locations

This course is designed for engineers developing software for platforms based around the ARM® Cortex®-M3 and Cortex-M4 processors, including an introduction to the Cortex Microcontroller Software Interface Standard (CMSIS) library. The course covers the ARM core range, programmer's model and Thumb-2 instruction set as well as the Cortex-M3/M4 Coresight debug architecture. It includes a number of worked examples and hands-on CMSIS compliant exercises to reinforce the lecture material.

Who should attend?

Software developers who wish to develop system and application software for ARM Cortex-M3 and Cortex-M4 processor based systems.

Pre-requisites

An in-depth knowledge of microprocessors is not essential, but would be advantageous. However, all participants must be computer literate and should have a basic understanding of the programming language C.

Training materials

The training materials for this class are based on ARM's own material. Doulos is a global ARM Approved Training Center.
