    Hi,

    let me say my personal opinions.

    1) Legacy ARM or ARMv7-A/R architecture is quite unique.
      - conditional execution for all instructions.
      - PC (program counter) is visible as a normal general register.
      - multiple load and store and theirs many transfer options.
      - No divide instruction in an early instruction set :-)

    2) Cortex-M (or ARMv6-M/ARMv7-M) is almost final form in embedded areas.
      - no other features would not be needed.
      - to be able to write almost all programs by only C language.

    3) ARMv8 is quite normal.
      - I have little interest to it.
      - I have interrest not to the architecture but to its implementations.

    Best regards,
    Yasuhiko Koumoto.
