Latest Patents

Caffo's latest patents include a "System for launching data on a bus by using first clock for alternately selecting data from two data streams and using second clock for launching data thereafter." This invention implements a bus interface apparatus and method that generates a pair of data streams from the data to be launched onto a data bus. Each stream is staged along a corresponding data path that includes multiple storage elements, feeding into a multiplexer (MUX). The MUX selects a data value for launching onto the bus based on a signal derived from an internal bus clock. The internal bus clock also generates a bus clock that is output to the bus along with the data.

Another significant patent is the "Method and system for detecting bypass errors in a load/store unit of a superscalar processor." This invention provides a load queue in a load/store unit that includes a real page number buffer for storing real page numbers for each instruction entry. The load queue also features a real page number comparator for comparing executing load instruction entries with queued load instruction entries. This system enhances the reliability of data processing by ensuring that queued load instructions are canceled when necessary.
