Abstract
A packet processor includes a memory and a programmable compute pipeline. The memory stores microcode that specifies respective sets for the packet types, and the respective set for each type specifies packet fields. The programmable compute pipeline includes a sequence of stages beginning with an initial stage. The initial stage includes an operand selector that extracts a data vector from each packet. The operand selector is programmable to extract the data vector that includes each field specified in the respective set for the type of each packet. Each stage except the initial stage inputs a first version of the data vector and each stage outputs a second version of the data vector. Each stage except the initial stage generates the second version of the data vector that replaces a part of the first version of the data vector with a result that the stage computes from the part.
