It's quite different though, Jazelle literally implemented java bytecode in hardware.
These instructions "merely" performs a float -> int conversion with JS semantics, such that implementations don't have to reimplement those semantics in software on ARM. The JS semantics probably match x86 so x86 gets an "unfair" edge and this is a way for ARM to improve their position.
