  • Security - pointer signing and landing pads  guide (coming soon) (Armv8.5-A introduced support for Branch Target Instructions (BTI). BTI support is controlled by the GP bit in the Stage 1 translation tables. Branch Target Instructions are discussed in this guide.
  • Armv8-A Instruction Set Architecture (Simple Sequential Execution (SSE)) 
  • Translation process: If are you are interested in the full details of translation process, it is described fully in pseudo code. The translation pseudo code is included with the XML for the instruction set. A good place to start is the AArch64.FullTranslate() function.

Describing memory in Armv8-A

Cacheability of instruction fetches are a bit more complicated than you might think. This topic is covered in Caches and Coherency guide (coming soon).

Note: For EL0 and EL1, this behavior can be partly overridden using the virtualization controls. This topic is covered in our Virtualization guide.

Cacheability and shareability attributes

Caches and cache coherency guide (coming soon). 

Combining Stage 1 and Stage 2 attributes

Stage 1 and Stage 2 translation are discussed in more detail in our Memory Management guide.
