The firm has considerable expertise in the processor architecture area, primarily related to X86 superscalar microprocessor architectures. Professionals in the firm have prepared and prosecuted patents related to all levels of processor architecture. For example, the firm has prepared and prosecuted patents related to instruction set architecture extensions (e.g. 3DNowTM and AMD64TM extensions). Additionally, the firm has prepared and prosecuted patents related to numerous processor microarchitectural features, including front end fetch mechanisms (e.g. branch prediction and other fetch prediction mechanisms), out of order execution mechanisms (e.g. reorder buffers, schedulers, register renaming mechanisms, etc.), caching mechanisms, power management features, etc.
