Latest Patents
Among his latest patents is a method and apparatus for synchronizing the use of buffer descriptor entries for shared data packets in memory. This invention focuses on techniques for synchronizing buffer descriptors for data packets transmitted over a network. It involves receiving private index data that indicates a specific buffer descriptor owned by a DMA controller. The process includes placing a write command on a memory exchange queue to change the owner to a different processor while incrementing the private index data. A public index is then determined, indicating the most recently changed buffer descriptor visible to the processor. In response to a request from the processor, the public index data is sent, allowing the processor to exchange data with buffer descriptors guaranteed to be owned by it.
Another significant patent is the header range check hash circuit, which efficiently searches a hash table containing multiple ranges. This technique reduces the number of searches needed to locate ranges stored in the hash table. The hash table is constructed so that each entry is associated with a different linked list, where each entry stores signature information and at least one pair of values defining a range. The technique modifies the signature based on preliminary range checks, resulting in a more even distribution of ranges among the linked lists. This innovation enhances the speed and efficiency of range searches, particularly in flow-based processing within network nodes like routers.
