    Hi,

    The latest 64-bit architecture can on both AArch64 and AArch32 state.

    Can someone tell me how to utilize this feature so that I can seamlessly integrate algorithms (which are optimized with 32-bit and 64-bit instructions) with applications which are…

    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?
