A Reconfigurable Network Topology for Medical Imaging
Inherent limitations on the computational power of sequential uniprocessor systems have lead to the development of parallel multiprocessor systems. The two major issues in the formulation and design of parallel multiprocessor systems are algorithm design and architecture design. The parallel multiprocessor systems should be so designed so as to facilitate the design and implementation of the efficient parallel algorithms that exploit optimally the capabilities of the system. From an architectural point of view, the system should have low hardware complexity, be capable of being built of components that can be easily replicated, should exhibit desirable cost-performance characteristics, be cost effective and exhibit good scalability in terms of hardware complexity and cost with increasing problem size. In distributed memory multiprocessor systems, the processing elements can be considered to be nodes that are connected together via an interconnection network. In order to facilitate algorithm and architecture design, we require that the interconnection network have a low diameter, the system be symmetric and each node in the system have low degree of connectivity. Further, it is also desirable that the system configuration and behavior be amenable to a suitable and tractable mathematical description. The requirement of network symmetry ensures that each node in the network is identical to any other, thereby greatly reducing the architecture and algorithm design effort. For most symmetric network topologies, however, the requirements of low degree of connectivity for each node and low network diameter are often conflicting. Low network diameter often entails that each node in the network have a high degree of connectivity resulting in a drastic increase in the number of inter-processor connection links. A low degree of connectivity on the other hand, results in a high network diameter which in turn results in high inter-processor communication overhead and reduced efficiency of parallelism. Reconfigurable networks attempt to address this tradeoff. In a reconfigurable network each node has a fixed degree of connectivity irrespective of the network size. The network diameter is restricted by allowing the network to reconfigure itself into different configurations. Broadly speaking, a reconfigurable system needs to satisfy the following criteria in order to be considered practically viable: (a) In each configuration the nodes in the network should have a fixed degree of connectivity irrespective of network size, (b) The network diameter should be kept low via the reconfiguration mechanism and (c) The hardware for the reconfiguration mechanism (i.e. switch) should be of reasonable complexity. In this presentation, we discuss our design of a reconfigurable network topology that is targeted at medical applications. We present some results and discuss the future roadmap of this project.

The Next Generation CDMA Technologies
Future wireless communication systems should be operating mainly, if not completely, for burst data services carrying multimedia traffics. The need to support high-speed burst traffic has already posed a great challenge to all currently available air-link technologies based on either TDMA or CDMA. The current CDMA technology has been widely used in both 2G and 3G mobile cellular standards and it has been suggested that it is not suitable for high-speed burst-type traffic. There are many problems with current CDMA technology, such as its low spreading efficiency, interference-limited capacity and the need for precision power control, etc. This talk will address various important issues about the next generation CDMA technologies as a major air-link technology for futuristic wireless applications. In particular, it will cover two major topics: why we need the next generation CDMA technologies, and what is the next generation CDMA technology.

Embedded Software Development with MDA

Model-Driven Architecture (MDA) is currently one of the most exciting approaches for accelerating code development and improving the quality of software in complex systems like embedded systems in ubiquitous era. MDA is an approach to the full lifecycle integration of enterprise systems comprised of software, hardware, humans, and business practices. It provides a systematic framework to understand, design, operate, and evolve all aspects of such enterprise systems, using engineering methods and tools. MDA utilizes models and a generalized idea of architecture standards to address integration of enterprise systems in the face of heterogeneous and evolving technology and embedded business domains. MDA combines computer-aided verification and machine intelligence during modeling to discover and remove design bugs before code reviews and testing. MDA represents an evolutionary step forward from previous development approaches. It’s built on the solid foundation of well established standards, including Unified Modeling Language (UML), the ubiquitous modeling notation used and supported by every major company in the software industry, and XML Metadata Interchange (XMI), the standard for storing and exchanging models using XML.

MDA is well-suited for embedded software development because it separates functional logic from implementation details and with the right MDA technology, automates the generation and testing of any embedded application architecture. MDA provides embedded software developers with a fundamentally different and higher-level way to accommodate changing requirements, increase reuse and extend system longevity.

In my talks, we will discuss the MDA and will help you understand what MDA is, how best to adopt it and the benefits it provides when implemented the embedded software with a model automation and transformation environment. We will also deliver the advantages of this approach as faster, more predictable software delivery cycles, minimizing the impact of requirements changes on development schedules, greater component reuse & implementation consistency and architectural flexibility and platform independences.
