RM1	Cortex-M1 implementation

This course covers the Cortex-M1 ARM core targetting FPGA SoCs

Objectives This course is split into 3 important parts: Processor architecture Software implementation Hardware implementation. A tutorial has been developed by ACSYS to facilitate the understanding of Cortex-M1 low level programming, therefore labs can be replayed after the course. The course explains how to design a SoC based on Cortex-M1, clarifying the operation of the interconnect and the debug facilities integrated in the CPU. Labs can be run under 2 possible environments: Eclipse/RVDS or Keil IDE For open courses, labs are run under Eclipse/RVDS. A more detailed course description is available on request at info@ac6-training.com

Prerequisites
	Knowledge of ARM7/9.
	This course does not include chapters on low level programming.
		ACSYS offers a large set of tutorials to become familiar with RVDS, assembly level programming, compiler hints and tips.
	More than 12 correct answers to Cortex-R prerequisites questionnaire.
