The ARMv8 Architecture Reference Manual, known as the ARM ARM, fully describes the ARMv8 instruction set architecture, programmer’s model, system registers, debug features and memory model. It forms a detailed specification to which all implementations of ARM processors must adhere.

ARM® Architecture Reference Manual - ARMv8, for ARMv8-A architecture profile (ARM DDI 0487).


In the event of a contradiction between this book and the ARM ARM, the ARM ARM is definitive and must take precedence. In most instances, however, the ARM ARM and the Cortex-A Series Programmer’s Guide for ARMv8-A cover two separate world views. The most likely scenario is that this book describes something in a way that does not cover all architecturally permitted behaviors, or simply rewords an abstract concept in more practical terms.
