WebJun 16, 2003 · “Thumb-2 core technology gives the developer the optimum balance of code density and performance, providing system designers with the freedom to create an entirely new generation of power-efficient and feature-rich embedded devices,” said Richard Phelan, Embedded CPU manager at ARM, in a statement. WebJun 15, 2024 · These instructions have a reach of approximately ±16MB. Windows uses Thumb-2 exclusively, so you won’t see the blx instruction used in this way. The X stands for “exchange”, which means that it swaps between Thumb-2 and classic ARM modes.² The return address is stored in lr, but with the bottom bit set. There’s a reason for this.

WebThis small number of formats allows for some regularity among instructions, and thus simpler decoder hardware, while also accommodating different instruction needs. Data-processing instructions have a first source register, a second source that is either an immediate or a register, possibly shifted, and a destination register.
