  • Publication number: 20190215021
    Abstract: Systems and methods in accordance with various embodiments of the present disclosure provide approaches for mapping entries to a cache using a function, such as cyclic redundancy check (CRC). The function can calculate a colored cache index based on a main memory address. The function may cause consecutive address cache indexes to be spread throughout the cache according to the indexes calculated by the function. In some embodiments, each data context may be associated with a different function, enabling different types of packets to be processed while sharing the same cache, reducing evictions of other data contexts and improving performance. Various embodiments can identify a type of packet as the packet is received, and lookup a mapping function based on the type of packet. The function can then be used to lookup the corresponding data context for the packet from the cache, for processing the packet.

  • Patent number: 10298496
    Abstract: A data or packet processing device such as a network interface controller may include cache control logic that is configured to receive a first request for processing a first data packet associated with the queue identifier, and obtain a set of memory descriptors associated with the queue identifier from the memory. The set of descriptors can be stored in the cache. When a second request for processing a second data packet associated with the queue identifier is received, the cache control logic can determine that the cache is storing memory descriptors for processing the second data packet, and provide the memory descriptors used for processing the second packet.

  • Patent number: 10228869
    Abstract: Techniques for controlling access to shared resources may include receiving multiple requests to access shared information associated with an identifier. For each of the requests, an entry in a linked list can be allocated to the request, and each entry can be associated with the identifier. The shared information associated with the identifier can be retrieved, and stored in each entry associated with the identifier. A conflict indicator is set in each entry to indicate whether the shared information is available for the request corresponding to the entry. The shared information stored in each entry is provided for each request after the conflict indicator in the corresponding entry indicates the shared information is available for the request.
