ARM Cortex-R4 Software Design is a 4-day comprehensive class that introduces the ARM® Cortex®-R4 architecture and the ARM development systems.
Software engineers designing applications for platforms based around the ARM Cortex-R4 processor Core.
Delegates should have a basic understanding of microprocessor systems and be familiar with assembler or C programming. A basic awareness of ARM and experience of embedded system development is helpful, but not essential.
This class uses training materials developed by ARM®
