NePSim: A Network Processor Simulator with Power Evaluation Framework

Introduction

There is an increasing interest in the NP architecture design as well as its power dissipation characteristics. However, there has not been an open-source simulation infrastructure that makes the performance/power tradeoffs in NPs clearly visible to computer architects.

NePSim is the first open source integrated infrastructure for analyzing and optimizing NP design and power dissipation at architecture-level. NePSim contains a cycle-accurate simulator for a typical NP architecture (Intel's IXP1200), an automatic verification framework for testing and validation, and a power estimation model for measuring the power consumption of the simulated NP. NePSim achieves satisfactory accuracy in both performance and power modeling.

NePSim is proudly highlighted in Intel IXA Summit and Intel IXA Newsletter 2004.

The Simulator

The NePSim 1.0 is available for non-commercial use only. This release does not include SRAM or SDRAM power model.

The verification tool (LOCGEN) can be downloaded from PAC.
