Modeling a Memory Subsystem with Petri Nets: a Case Study
- . Memory subsystems often turn out to be the main performance bottleneck in current computer systems. Nevertheless, the architectural features of common RAM chips are not utilized to their limits. Therefore, a complex Petri Net model of a memory subsystem was developed and investigated to explor

Methods for Evaluating and Covering the Design Space during Early Design Development
- This paper gives an overview of methods used for Design Space Exploration (DSE) at the system- and micro-architecture levels. The DSE problem is considered to be two orthogonal issues: (I) How could a single design point be evaluated, (II) how could the design space be covered during the explorat

Design Space Exploration of Network Processor Architectures
- We describe an approach to explore the design space of architectures of packet processing devices on the system level. Our method is specific to the application domain of network packet processors and is based on (1) models for packet processing tasks, a specification of the workload generated by tr

Modular reference implementation of an IP-DSLAM
- We describe a modular reference implementation of an IPbased DSL access multiplexer (DSLAM). We identify deployment trends and primary tasks a future DSLAM has to offer. The implementation is representative of applications in access networks and indicative of real-world performance. To accomplish th

Exploring Trade-offs in Performance and Programmability of Processing Element Topologies for Network Processors
- Network processors exploit task and packet level parallelism to achieve high throughput. To date, this has resulted in a huge diversity of architectures for similar applications. One of the main differences among network processors is the inter-connection topology between processing elements. This t

Supporting a Low Delay Best-Effort Class in the Presence of Real-Time Traffic
- In this paper we propose a packet scheduler to provide a low delay service to best-effort packets without jeopardizing the delay bounds associated with real-time flows. We show that some of the well known service mechanisms for integrating soft real-time tasks into a hard real-time environment, such

Comparing Analytical Modeling with Simulation for Network Processors: A Case Study
- Programming network processors remains an art due to the variety of different network processor architectures and due to little support to reason and explore implementations on such architectures. We present a case study of mapping an IPv4 forwarding switch application on the Intel IXP1200 network p

A Framework for Evaluating Design Tradeoffs in Packet Processing Architectures
- We present an analytical method to evaluate embedded network packet processor architectures, and to explore their design space. Our approach is in contrast to those based on simulation, which tend to be infeasible when the design space is very large. We illustrate the feasibility of our method using

Reusing Design Experience for Petri Nets Through Patterns
- Industrial applications of Petri nets for modeling and design often result in very complex models (Zurawski and Zhou 1994; Esser, Janneck, and Naedele 1997). Designers can handle this complexity much better if they can (re)use structures expressing expert modeling experience at a higher level of des
