  • Title

The Role of Functional Memories in Parallel Information Processing with Localized and Distributed Systems

  • Authors

  • Abstract

The analysis of parallel information-processing systems, independent of their realization in localized or distributed form, reveals that the necessary data exchange between data-storage and data-processing parts of the system represents a major limiting factor for the system performance. Therefore, in addition to the number-crunching power of the processing parts, innovations which substantially improve the bandwidth of the data exchange are essential for advances in the overall system capabilities. To be practically useful, such innovations must in particular carefully balance the bandwidth of the exchanged data amount against the required power dissipation for this purpose. We will review the main methods for achieving the data- exchange improvements, namely (a) an increased memory-access bandwidth by multi-porting of the memory and (b) a unification of memory and processing parts of the information-processing system. We will further present the recent advances in VLSI architectures for realizing the higher data-exchange bandwidth by applying advanced nano-technologies and discuss practical implementation examples for parallel processors as well as for pattern-matching and pattern-recognition systems.

Pains and Challenges in the Mobile Internet Evolution

  • Summary

The Mobile Internet evolves drastically in the last decade in Japan. The rapid evolution provides pains and challenges for operators, content providers, and client software technology providers. The CPU and memory size evolve in a scale of thousand times. Display resolution evolves in a slightly modest manner. Restrictions, the speed of change, and the diversity of capabilities continues to provide challenges to software engineering and service engineering.

The author will summarize the decade of challenges in software engineering in the mobile handset client side. There are 4 billion mobile handsets on this planet and the media and service impacts of them will exceed those of PCs and TVs. The lessons learned in the mobile Internet evolution about mobile service engineering will be highlighted.

Computing with Membranes: An Overview

  • Abstract

Membrane computing is a branch of molecular computing that aims to develop models and paradigms that are biologically motivated. It identifies an unconventional computing model, namely a P system, which abstracts from the way living cells process chemical compounds in their compartmental structure. P systems are a class of distributed maximally parallel computing devices of a biochemical type. We present an overview of the area and discuss recent results that answer some interesting and fundamental open questions concerning these systems.
