  • Trace indexing via trace end addresses
    Patent number: 7802077
    Abstract: A new class traces for a processing engine, called “extended blocks,” possess an architecture that permits possible many entry points but only a single exit point. These extended blocks may be indexed based upon the address of the last instruction therein. Use of the new trace architecture provides several advantages, including reduction of instruction redundancies, dynamic block extension and a sharing of instructions among various extended blocks.
