Cortex®-M23, M33: Armv8-M Architecture Training for Trainees with Knowledge of the Previous Version

Get familiar with the new Armv8-M architecture (Cortex®-M23 and -M33) and learn how to write software in C and Assembler. This workshop focuses on software and covers a variety of topics, such as the TrustZone, processor architecture, extended instruction set, exception behavior, and many more. After the training, you can locate programs in memory in secure and non-secure configuration and test them - the perfect start for designing Cortex®-M23/M33 based systems.

Teilnehmer

The training addresses software and hardware developers with a basic knowledge of the previous architecture (Armv6-M/ Armv7-M architecture of the Cortex®-M0/M0+/M3/M4 or -M7).

Voraussetzungen

Basic knowledge of the Armv6-M/ Armv7-M architecture of the Cortex®-M0/M0+/M3/M4 or -M7 as well as basic knowledge of ANSI-C and microcontrollers is required. The training focuses on the new features offered by the Cortex®-M23, M33 and the Armv8-M architecture.
