    I'm trying to configure the performance counters for the Cortex-A57 and I'm very confused. The technical reference manual alludes to accesses being…

  • Porting to Arm 64-bit

    This white paper is an introduction to porting existing code to the A64 instruction set supported by Armv8-A processors like the Cortex-A53 and Cortex-A57 from Arm. It will also be useful for those writing new code for these platforms.

    Why 64-bit?
