Abstract
Approaches for processing packets having variable size fields. In one approach, an extraction circuit determines a size of a variable size field in the packets. A plurality of operation circuits access fields of the packets, and each operation circuit includes a control circuit that determines positions of fields in the packets. The position of an accessed field in a packet varies according to changes in size of the variable size field. A reconfiguration circuit is coupled to the extraction circuit and to the control circuit of each of the operation circuits. The reconfiguration circuit is responsive to a change in size of the variable size field from one packet to the next and reconfigures the control circuit of an operation circuit to correctly determine the field positions in the next packet.
