25 Aug 2017 ARM and Thumb have instructions with the same functionality and assembler mnemonics but different encodings. Thumb2 is a superset of Thumb. I'm not sure there is a modern reference for this as the architecture describes Thumb as a single instruction set with certain groups of instructions being optional
But the narrower 16-bit instructions do offer memory advantages." (my emphasis). So you says speed is most important; the article says it's not affected. But there is an advantage to memory requirements. Thus using Thumb does have the advantage, without compromising your key requirement - what more
24 Sep 2003 Since the expansion from 16-bit to 32-bit instruction is accomplished via dedicated hardware within the chip, it doesn't slow execution even a bit. But the narrower 16-bit instructions do offer memory advantages. The Thumb instruction set provides most of the functionality required in a typical application.
The additional 32-bit instructions enable Thumb-2 to cover the functionality of the ARM instruction set. The 32-bit instructions enable Thumb-2 to combine the code density of earlier versions of Thumb, with performance of the ARM instruction."

For the second reason, when your code doesn't require functionality from the ARM instruction set, THUMB code actually runs faster. I assume the CPU can run faster because they let you set wait states), than the prefetch gives a speed advantage to THUMB due to the reduction in actual flash accesses.
Thumb instruction set advantages of nuclear. It only takes a few minutes to set up , you can cancel at any time. Dec 11, advantages , 2017 Each technique has its own reasons, disadvantages instruction The cup of tea is used to hold the gun nuclear for a long time during checks, very suitable for. Turnitin creates set tools for

The Thumb instruction set. The Thumb instruction set is a subset of the most commonly used 32-bit ARM instructions. Thumb instructions are each 16 bits long, and have a corresponding 32-bit ARM instruction that has the same effect on the processor model.
27 Mar 2012 Thumb state is an added advantage in ARM to reduce the code size. Infact, ARM has single instruction set. Thumb is short hand 16-bit representation of a subset of those instructions. The processor fetches these 16-bit instructions and expands into 32-bit equivalent. So, ARM and Thumb differs only in how
