Abstract
An apparatus and method for a processor microarchitecture that quickly and efficiently takes large steps through program segments without fetching all intervening instructions. The microarchitecture processes descriptors of trace sequences in program order so as to locate and dispatch descriptors of dependence chains that are used to fetch and execute the instructions of the dependence chain in data flow order.
