With a total of 2 patents, his work has had a profound impact on the efficiency of multiprocessor systems.

Latest Patents

One of Bradford's latest patents is titled "Interlock for controlling processor ownership of pipelined data." This invention ensures data integrity in process ownership indications by providing an ownership interlock on the data units in a pipeline to a store-in type of cache. The ownership interlock prevents any processor ownership change from occurring until all outstanding stores have been made in the cache data unit. This innovation allows for a continuous flow of stores into and out of the pipeline, expediting ownership changes without halting processor operations.

Another significant patent is the "Bias filter memory for filtering out unnecessary interrogations of cache." This invention filters out many unnecessary interrogations of the cache directories of processors in a multiprocessor system. By doing so, it reduces the required size of the buffer invalidation address stack (BIAS) and increases the efficiency of each processor. The filter memory records cache block addresses in invalidation requests and manages them effectively to prevent unnecessary cache interrogations.
