  • Patent number: 11588734
    Abstract: Described are programmable input output (IO) devices comprising: an match processing unit (MPU) and a memory unit. The MPU comprising at least one arithmetic logic unit (ALU). The memory unit having instructions stored thereon which, when executed by the respective programmable IO device, cause the programmable IO device to perform operations. These operations comprise: receiving, from an inbound interface, a packet comprising packet data for at least one range-based element; determining, via the MPU, a lookup result by performing a modified binary search on an interval binary search tree with the packet data to determine a longest prefix match (LPM), wherein the interval binary search tree maps the at least one range-based element to an associated data element; and classifying the packet based on the lookup result.

  • Publication number: 20220060419
    Abstract: Described are programmable IO devices configured to perform operations. These operations comprise: determining a set of range-based elements for a network; sorting the set of range-based elements according to a global order among the range-based elements; generating an interval table from the sorted range-based elements; generating an interval binary search tree from the interval table; propagating data stored in subtrees of interior stages of the interval binary search tree to subtrees of a last stage of the interval binary search tree such that the interior stages do not comprise data; converting the interval binary search tree to a Pensando Tree; compressing multiple levels of the Pensando Tree into cache-lines; and assembling the cache-lines in the memory unit such that each stage can compute an address of a next-cache line to be fetched by a next stage.
