Cortex-M Architecture
Introduction
In this chapter, we will take a closer look at the Cortex-M processor architecture. The bulk of this chapter will concentrate on the Cortex-M3 processor. Once we have a firm understanding of the Cortex-M3, we will look at the key differences in the Cortex-M0, M0+, and M4. There are a number of exercises throughout the chapter. These exercises will give you a deeper understanding of each topic and can be used as a reference when developing your own code.
Cortex-M Instruction Set
As we described in Chapter 1, the Cortex-M processors are Reduced Instruction Set Computer (RISC)-based processors and as such have a small instruction set. The Cortex-M0 has just 56 instructions, the Cortex-M3 has 74, and the ...
