Thumb code is able to provide up to 65% of the code size of Arm, and 160% of the performance of an equivalent Arm processor connected to a 16-bit memory system.

Thumb ensures smaller operands in part by restricting most of its instructions to use 8 general purpose registers in place of the usual 15. A few instructions ...

2023/3/9 -Thumb instruction set encoding is a feature of the ARM architecture that allows you to execute 16-bit instructions on a 32-bit processor.

Thumb mode allows for code to be smaller, and can potentially be faster if the target has slow memory. Please consult documentation from your MCU vendor, or.
