In some embodiments, a method and apparatus for automatically parallelizing a sequential network application through pipeline transformation are described. In one embodiment, the method includes the configuration of a network processor into a D-stage processor pipeline. Once configured, a sequential network application program is transformed into D-pipeline stages. Once transformed, the D-pipeline stages are executed in parallel within the D-stage processor pipeline. In one embodiment, transformation of a sequential application program is performed by modeling the sequential network program as a flow network model and selecting from the flow network model into a plurality of preliminary pipeline stages. Other embodiments are described and claimed.

Apparatus and method for automatically parallelizing network applications through pipelining transformation

Automatic software controlled caching generations in network applications are described herein. In one embodiment, a candidate representing a plurality of instructions of a plurality of threads that perform one or more external memory accesses is identified, where the external memory accesses have a substantially identical base address. One or more directives and/or instructions are inserted into an instruction stream corresponding to the identified candidate to maintain contents of at least one of a content addressable memory (CAM) and local memory (LM) of a processor, and to modify at least one of the external memory access to access at least one of the CAM and LM of the processor without having to perform the respective external memory access. Other methods and apparatuses are also described.

Automatic caching generation in network applications

A program may be partitioned into at least two stages, where at least one of the stages comprises more than one parallel thread. Data required by each of the stages, which data is defined in a previous stage may be identified. Transmission of the required data between consecutive stages may then be provided for.

Live set transmission in pipelining applications

A compiler includes a location-assigning module to optimally allocate register locations in various memory blocks of a memory during compilation of a program code in accordance with code proximity of the program code in accessing the register locations and size of each of the memory blocks.
