In a multi-streaming processor having a memory cache, a system for fetching instructions from individual ones of multiple streams to an instruction pipeline is provided, comprising a fetch algorithm for selecting from which stream to fetch an instruction, and a hit/miss predictor for forecasting whether a load instruction will hit or miss the cache. The prediction by the hit-miss predictor is used by the fetch algorithm in determining from which stream to fetch. A hit prediction results in a next instruction being fetched from the same stream as the instruction tested by the hit/miss predictor, while a miss prediction results in the next instruction being fetched from a different stream, if any. The predictor is also used to determine which instructions to dispatch to functional units.
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
