WebFeb 10, 2013 · ARM has two different instruction encoding modes: ARM and THUMB. In ARM mode, you get access to all instructions, and the encoding is extremely simple and fast to decode. Unfortunately, ARM mode code tends to be fairly large, so it's fairly common for a program to occupy around twice as much memory as Intel code would. WebThe _____ instruction set has the code density performance close to the original Thumb instruction set, but also the execution performance close to that of the ARM instruction set. Thumb2 The Cortex-M profile microcontrollers are based on a 32-bit _____ instruction set computer architecture.
WebApr 3, 2024 · ARM has multiple instruction sets: A32 (32 bit long instructions) and mixed-length T32 (either 32 bit or 16 bit long instructions). T32 was called Thumb before ArmV8. While 16 bit instructions reduce code size, 32 bit instructions can have higher performance. WebDocumentation – Arm Developer
