Refer to Table Condition Field {cond} Refer to Table Operand 2 Refer to Table PSR fields Updates condition flags if S present Flag is unpredictable after these instructions in Architecture v4 and earlier Sticky flag. Always updates on overflow (no S option). Read and reset using MRS and MSR B ARM is a family of Reduced Instruction Set Computer (RISC) architectures for computer processors that has become the predominant CPU for smartphones Unfortunately support for structures in GAS isn't great. Understandably, many of the hand-written assembly programs for Linux normally use Basics of ARM7 Instructions/Programming.Instruction and Instruction SetRISC and CISC InstructionsARM instruction setARM Instruction FormatARM addressing • Modern ARM processors have several instruction sets: • The fully-featured 32-bit ARM instruction set, • The more restricted, but space efficient, 16-bit Thumb instruction set, • The newer mixed 16/32-bit Thumb-2 instruction set, • Jazelle DBX for Java byte codes, • The NEON 64/128-bit SIMD ARM is a family of instruction set architectures based on RISC architecture developed by a single company - ARM Holdings. Because ARM is a family of architectures and not a single architecture, it can be found in large scale of electronic devices (from simple small embedded systems with ARM MCUs Pseudocode details of ARM core register operations. A2.3.2 The Application Program Status Register. A4.1 About the instruction set. A4.1.1 ARMv6-M and interworking support. A4.1.2 Conditional execution. E.6 Statements and program structure. An instruction set extension to ARM. • The A64 instruction set provides some significant performance benefits, including a larger register pool. The additional registers and the ARM Architecture Procedure Call Standard (AAPCS) provide a performance boost when you must pass The additions provide ARM equivalents of instructions supported in the Thumb instruction set. The precise effects of each new instruction are described Chapter 3 The Thumb Instruction Set Gives a description of the Thumb-2 extension to the ARM and Thumb instruction sets, organized by type of ARM instruction set overview. All ARM instructions are 32 bits long. These instructions are used to: • branch backwards to form loops • branch forward in conditional structures • branch to subroutines • change the processor from ARM state to Thumb state. ARM Addressing Modes Quick Reference Card. Operation Parallel Halfword-wise addition arithmetic Halfword-wise subtraction. and change to Java state.
