摘要： A method is provided for generating a hardware description language (HDL) specification of a network packet processor from a textual language specification of the processing of network packets by the processor. The processor includes a look-ahead stage, an operation stage, an insert/remove stage, and an interleave stage. The textual language specification identifies the ports of the processor. The textual language specification includes formats for the type or types of the incoming and outgoing network packets. Each format includes the fields of the type of network packet. The textual language specification includes a procedure for each input port and for each type of incoming network packet received at the input port. Each procedure includes one or more actions for modifying the fields of a type of network packet as a function of state data and/or the fields of the type of network packet.

摘要： A method is provided for simulating a processor of network packets. A specification is input for the processor. The specification includes actions specifying a modification of the network packets by the processor. Each action includes a guard condition that enables and disables the action. First and second values of certain fields are determined for each action. The guard condition enables and disables the action respectively for the first and second values of the fields. The network packets are generated. For each field included in the guard conditions, a value of the field is selected for each generated network packet from the values of the field within the first and second values for the actions. The specification of the processor is translated into a simulator of the processor. The modification of the network packets is simulated in the simulator. A result of the modification is displayed on a user interface.

摘要： A state machine circuit converts a first network packet into a second network packet according to modification actions from a textual language specification. Each modification action is either an insertion action inserting a data segment or a removal action removing a data segment. Each state corresponds to a pairing of a first data word from the first packet and a second data word from the second packet. Each state selects the data units of the second data word from the data segment of each insertion action and the data units of both the first and a prior data word. Each state specifies one or more next states including the state corresponding to the pairing of either the first or a next data word after the first data word in the first sequence and either the second or a next data word after the second data word in the second sequence.

摘要： From source code specification of each of a plurality of threads, those variables of a data structure referenced by the thread are determined. For each thread, a respective adaptation of the source code specification of the data structure is generated. Each adaptation includes only variables of the data structure that are referenced in the respective thread. The source code specifications of the threads are compiled into respective object code segments using the respective adaptations of the data structures. Each object code segment requires memory space for the data structure for only those variables included in the respective adaptation. The source code specification of the data structure describes a network packet, and the respective object code segments are configured to operate on the respective portions of the network packet stored in separate memories while executing on respective processors.

摘要： A pipeline is provided for processing network packets. The pipeline includes a look-ahead stage, an operation stage, an insert/remove stage, and an interleave stage. The look-ahead stage synchronizes two or more fields of a network packet. The operation stage modifies one or more of the fields of the network packet. The operation stage may modify state data and the fields of the network packet as a function of the state data and the fields. The insert/remove stage performs data insertion and removal at one or more fields of the network packet. The interleave stage ensures that the modified network packet follows rules for interleaving network packets. The look-ahead, operation, insert/remove, and interleave stages are generated from a textual language specification of the processing of the network packets by the pipeline.
