Abstract
A method and apparatus is provided for restoring a free physical register list to its previous state without having to physically restore any data. The method and semiconductor device utilizes sets of pointers to manage physical register pointers in the physical register list. The physical register list is able to independently track physical registers for multiple threads of a multithreading microprocessor.
