What you’ll learn

Introduction to ARM Cortex M3 and M4 Processors

  • Take a look at the ARM Cortex-M Processor’s structure to learn more.
  • Understand how ARM processors can be used.
  • Use the ARM Cortex-M ISA to understand and write Assembly Language Programs that work.


  • It doesn’t matter how little you know about electronics.


Hi all! Welcome to my course on ‘Introduction to ARM Cortex M3 and M4 Processors’. This course will help you gain knowledge in the architecture, registers, features of ARM Cortex Processors. The other half of the course will help you understand the instruction set of ARM Cortex-M so that you’ll be able to write programs in assembly language.

What are you waiting for? I’ll see you there in my course.

The Cortex-M3 and Cortex-M4 are processors designed by ARM. The Cortex-M3 processor was the first of the Cortex generation of processors, released by ARM in 2005 (silicon products released in 2006).

The Cortex-M4 processor was released in 2010 (released products also in 2010). The Cortex-M3 and Cortex-M4 processors use a 32-bit architecture. Internal registers in the register bank, the data path, and the bus interfaces are all 32 bits wide. The Instruction Set Architecture (ISA) in the Cortex-M processors is called the Thumb ISA and is based on Thumb-2 Technology which supports a mixture of 16-bit and 32-bit instructions
