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.

Trace indexing via trace end addresses

Fusing micro-operations (uops) together. Intra-instruction fusing can increase cache memory storage efficiency and computer instruction processing bandwidth within a microprocessor without incurring significant computer system cost. Uops are fused, stored in cache memory, un-fused, executed in parallel, and retired in order to optimize cost and performance.
