摘要： A method of estimating performance of a design can include selecting a segment of the design for hardware emulation within an emulation system implemented within an integrated circuit. The emulation system can include a generic accelerator coupled to a processor of the integrated circuit. The method further can include modifying the design, using a processor of a host system, to invoke the generic accelerator in lieu of executing the selected segment within the processor of the emulation system during emulation.

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： 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.
