The design for a routing table circuit for Ethernet-, IP- and ATM-applications is presented. Starting point for the design was an object-oriented general behavior of the routing table. The selected data structure for the routing table is based on a modification of the structure denominated trie, saving one search level and memory space. The architecture for searching and sorting of data, implemented in hardware, is explained. This modified trie stores 64 K addresses and the associated data, achieving a high performance too. The circuit, which can support a flow of 500000 frames/s, is connected to the PCI Bus. For the implementation a FLEX10K100 from Altera Company was used.

Modelling Process

Biological nervous systems and the mechanisms underlying their operation exhibit astonishing complexity. Computational models of these systems have been correspondingly complex. As these models become ever more sophisticated, they become increasingly difficult to define, comprehend, manage and communicate. Consequently, for scientific understanding of biological nervous systems to progress, it is crucial for modellers to have software tools that support discussion, development and exchange of computational models. We describe methodologies that focus on these tasks, improving the ability of neuroscientists to engage in the modelling process. We report our findings on the requirements for these tools and discuss the use of declarative forms of model description—equivalent to object–oriented classes and database schema—which we call templates. We introduce NeuroML, a mark–up language for the neurosciences which is defined syntactically using templates, and its specific component intended as a common format for communication between modelling–related tools. Finally, we propose a template hierarchy for this modelling component of NeuroML, sufficient for describing models ranging in structural levels from neuron cell membranes to neural networks. These templates support both a framework for user–level interaction with models, and a high–performance framework for efficient simulation of the models.

Object Storage

An efficient object manager, a middle layer on top of a storage system, is essential to ensure acceptable performance of object-oriented database systems, since a traditional record-based storage system is too simple to provide object abstraction. In this chapter, we design and implement an extensible object storage system, called Soprano, in an object-oriented fashion which has shown great potential in extensibility and code reusability. Soprano provides a uniform object abstraction and gives us the convenience of persistent programming through many useful persistent classes. Also, Soprano supports efficient object management and pointer swizzling for fast object access. This chapter investigates several aspects of the design and implementation of the extensible object storage system. Our experience shows the feasibility of using an object-oriented design and implementation in building an object storage system that should have both extensibility and high performance.

Performance Computing

The development of the Virtual Reality (VR) techniques for visualizaton of the computational simulations of complex problem has opened some new avenues for heat transfer and fluid flow research. The importance of data visualization is clearly recognized for to better understanding of the 3-D nature of the flow fields. This work introduces the educational user friendly “VRJET” package designed for teaching fluid mechanics and heat transfer. A Software is developed with C++ standard Programming language using an object-oriented approach to visualize the flow field with high performance computing including advanced support for data presentation and navigation techniques through 3D virtual environment. This work deals with 3-D visualization of the data of impinging laminar single square jet on a heated flat surface, obtained from numerical simulation. This package can be used for research, educational, and engineering.
