In this paper, we compare the features of various Cortex-M processors and highlight considerations for selecting the correct processor for your application. The paper includes detailed comparisons of the Cortex-M instruction sets and advanced interrupt capabilities, along with system-level features, debug and trace features, and performance comparisons.
Cortex-M processors, and how they compare to other ARM processors. 1.1 The ARM processor family Over the years, ARM has developed quite a number of different processor products. In the following diagram (Figure 1), the ARM processors are divided between the classic ARM processors and the newer Cortex processor product range.
