The ARM processor (Thumb-2), part 1: Introduction

WebSome instructions use the least significant bit of the address to determine whether the code being branched to is Thumb code or ARM code. Before the introduction of 32-bit Thumb instructions, the Thumb instruction set was limited to a restricted subset of the functionality of the ARM instruction set. Almost all Thumb instructions were 16-bit. WebThe Thumb-2 set includes both 16- and 32-bit instructions. Its functionality is almost identical to that of the ARM instruction set. In this tutorial we will deal only with the ARM instruction set. We should note that there exists a Unified Assembler Language (UAL), which provides a common syntax for ARM and Thumb instructions. It supersedes ... WebSep 19, 2024 · An ARM processor (assuming it supports both instruction sets) is in either ARM mode or in Thumb mode. This "mode" is set in the low bit of the instruction address (register PC ), but it is not as simple as that instructions at an odd address are Thumb and instructions at an even address are ARM. rock a billy clothes
