Nope, not until now. It seems to be a much more modern take on the idea of an object oriented CPU architecture.
Yet, there is something about object oriented ISA's that has made CPU designers eschew them consistently. Ranging from the Intel iAPX-432, to the Japanese Smalltalk Katana CPU, to jHISC, to another, unrelated, Katana CPU by the University of Texas and the University of Illinois, none of them have ever yielded a mainstream OO CPU. Perhaps, modern computing is not very object oriented after all.
