Abstract
A multi-slice processor comprising a high-level structure and history buffer. Write backs are no longer associated with the history buffer and the history buffer comprises slices determined by logical register allocation. The history buffer receives a register pointer entry and either releases or restores the entry with functional units comprised in the history buffer.
