ARM instruction set

Thumb instruction set

The processor executes three instruction sets: 32-bit ARM instruction set

16-bit Thumb instruction set

8-bit Java instruction set

The ARM instruction set allows a program to achieve maximum performance with the minimum number of instructions. The majority of instructions are executed in a single cycle.

The Thumb instruction set is simpler than the ARM instruction set, and offers increased code density for code that does not require maximum performance. Code can switch between ARM and Thumb instruction sets on any procedure call.
