Latest Patents

Haldun Umur Darbaz holds a patent titled "Least Recently Used Ranking in a Multi-Port Cache." This invention includes an apparatus that features a cache controller circuit and a multi-ported cache memory comprising a plurality of cache ways. The cache controller circuit is designed to maintain rank values and a threshold value that can be used to classify these rank values. A specific rank value corresponds to the least recently used cache way among the plurality. The cache controller circuit is also configured to receive first and second memory access requests during a common access cycle. In response to determining that these requests correspond to respective cache ways, it compares the rank values to the threshold value. Based on this comparison, the circuit modifies the rank value of a selected cache way.
