Although these primitives are part of the NetPDL specification, a separate document has been created due to the (relative) complexity of these constructs. text/html 2011-11-04T18:55:08+01:00 icerrato http://www.nbee.org/doku.php?id=netpdl:core_specs&rev=1320429308&do=diff Language Basics Before describing the NetPDL language in depth, a brief overview of the language itself is presented. <netpdl>: the root element A NetPDL file starts with the <netpdl> root element, which supports the following attributes in addition to the ones: text/html 2011-11-02T17:01:13+01:00 icerrato http://www.nbee.org/doku.php?id=netvm:coprocessors&rev=1320249673&do=diff The NetVM model includes the concept of virtual coprocessors, i.e. abstract components providing special purpose functionalities that are often implemented in hardware on many network processor architectures (e.g. Content Addressable Memories for fast table lookups, Deterministic Finite Automata coprocessors for string and regular expression matching). A coprocessor is viewed by the application as a black box providing specific operations and, while its coherent interface guarantees the portabil…
