Latest Patents

John De Rosa holds a patent for a "Method and apparatus for sharing data between processors in a computer." This invention introduces a cache coherency scheme in a multiprocessor computer system that allows for fast data sharing between caches. The new cache coherency state enables a processor pair to share data more effectively and eliminates the need for bus transfers, thereby improving system throughput. The transfer of data is achieved by returning a portion of a preselected data block in response to either a read or a read for ownership request by one of the processors. The ownership of this data block is shared between the processor pair, with both processors indicating that the preselected data block is incomplete.
