Latest Patents

Fernando's latest patents include innovative systems and methodologies. One notable patent is titled "Acquiring instruction addresses associated with performance monitoring events." This invention describes systems, methodologies, media, and other embodiments related to acquiring instruction addresses linked to performance monitoring events. An exemplary system embodiment includes logic for recording instruction and state data associated with events countable by performance monitoring logic in a pipelined processor. Additionally, the system may include logic for traversing the instruction and state data based on cycle counts and retirement counts.

Another significant patent is the "Method and apparatus for reducing branch prediction table pollution." This invention involves a branch target structure that predicts a branch target address for an instruction flow. To conserve space, only a portion of the branch target address is stored. The branch target address is reconstructed by assuming that an unspecified portion of the current branch instruction address matches corresponding bits of the branch target address. A comparator determines if this unspecified portion matches. If it does not match, the update of the branch target structure is inhibited; otherwise, the update is allowed.
