RISC vs. CISC wars raged in the 80s and its debatable if
the question was ever settled. With the proliferation of tablets,
smartphones which run ARM (a RISC ISA) compared to desktops,laptops
which run x86 (a CISC ISA), the question of whether ISA plays a role
in performance or energy efficiency is becoming important again. In
this talk, we examine and analyse in detail several implementations of
the ARM and x86 ISA to provide a definitive answer to this decades old
question of RISC vs. CISC.

Much of this work is on-going and feedback (aka criticism) on all

aspects of this work are welcome
