ABSTRACT:
A method for emulating a nexthop instruction in microcode with the assistance of dedicated hardware to extract read and write addressing from the nexthop instruction instead of performing this operation in microcode. A method for emulating a nexthop instruction in microcode with the assistance of dedicated hardware to compare a nexthop read address to a special value and to indicate whether the nexthop read address matches the special value, instead of performing this operation in microcode. A method for determining a network address by performing a single extraction of bit fields of a tree instruction to allow multiple tree search processes to be performed.
