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 and system for concurrent data processing, and an integrated circuit having programmable logic therefor, are described. A multi-threaded application is parsed into respective threads. Data value variables, data operators, data processing order of execution, and data result variables are identified from the threads. A code listing is generated associated with each of the threads for the data value variables, the data operators, the data processing order of execution, and the data result variables identified. Source and destination address information is associated with the data value variables and the data result variables. The source and destination address information is ordered to preserve the data processing order of execution. A configuration bitstream is generated for instantiating thread-specific processors in programmable logic, the thread-specific processors associated with the threads each having at least a portion of the data operators.

摘要： A configurable memory manager is configurable with various configuration parameters. The configurable memory manager has client ports for receiving requests for accessing memories and memory ports for accessing respective memories. The client and memory ports are each independently configurable to specify the parameter of a data width of the port. The configurable memory manager includes a switch and a translator. The translator translates a virtual address in each of the requests into an identifier of one of the memories and a physical address in the memory. The switch transfers each request from the client port receiving the request to the memory port for accessing the memory identified by the identifier for the virtual address in the request.
