ARM Cortex-M3/M4 Software Design
Standard Level - 3 daysview dates and locations
This course is designed for engineers developing software for platforms based around the ARM® Cortex®-M3 and Cortex-M4 cores, including an introduction to the Cortex Microcontroller Software Interface Standard (CMSIS) library. Additionally, the course covers the ARM core range, programmer's model, Thumb-2 instruction set as well as the Cortex-M3/M4 Coresight debug architecture. The course 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.
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.
The training materials for this class are based on ARM's own material. Doulos is a global ARM Approved Training Center.
