Abstract
A method is provided for scheduling a network packet processor. A textual language specification is input of the processing of network packets by the network packet processor. The textual language specification includes memory read actions and modification actions. Each memory read action reads a stored value from a memory of the network packet processor. Each modification action modifies a field of the network packets. An availability is determined for each field read from the network packets for the memory read and modification actions. An availability is determined for each stored value read from the memory for the memory read actions. A look-ahead interval is determined from the availabilities. A respective storage class is determined for the fields for the memory read and modification actions. The respective storage class is one of a bus, a register, and a register with bypass.
