  • GnatDb: A Small-Footprint, Secure Database System
    2002
    Co-Authors: Radek Vingralek
    Abstract:

    This paper describes GnatDb, which is an embedded database system that provides protection against both accidental and malicious corruption of data. GnatDb is designed to run on a wide range of Appliances, some of which have very limited resources. Therefore, its design is heavily driven by the need to reduce resource consumption. GnatDb employs atomic and durable updates to protect the data against accidental corruption. It prevents malicious corruption of the data using standard cryptographic techniques that leverage the underlying log-structured storage model. We show that the total memory consumption of GnatDb, which includes the code footprint, the stack and the heap, does not exceed 11 KB, while its performance on a typical Appliance Platform remains at an acceptable level

  • system and apparatus for eyeglass Appliance Platform
    2010
    Co-Authors: David Chaum
    Abstract:

    The present invention relates to a personal multimedia electronic device, and more particularly to a head-worn device such as an eyeglass frame having a plurality of interactive electrical/optical components. In one embodiment, a personal multimedia electronic device includes an eyeglass frame having a side arm and an optic frame; an output device for delivering an output to the wearer; an input device for obtaining an input; and a processor comprising a set of programming instructions for controlling the input device and the output device. The output device is supported by the eyeglass frame and is selected from the group consisting of a speaker, a bone conduction transmitter, an image projector, and a tactile actuator. The input device is supported by the eyeglass frame and is selected from the group consisting of an audio sensor, a tactile sensor, a bone conduction sensor, an image sensor, a body sensor, an environmental sensor, a global positioning system receiver, and an eye tracker. In one embodiment, the processor applies a user interface logic that determines a state of the eyeglass device and determines the output in response to the input and the state.

  • design and implementation of a network centric Appliance Platform
    2012 Brazilian Symposium on Computing System Engineering, 2012
    Co-Authors: Davide Pasetto, Hubertus Franke, Kai Schleupen, D Maze, Hartmut Penner, Heather D Achilles, Catherine H Crawford, Mark Purcell
    Abstract:

    Increasing demands on end-to-end solution performance has lead to a generation of workload optimized systems and Appliances, with tightly integrated hardware and software delivering substantial improvements over general purpose architectures. Among the many challenges encountered in designing an Appliance, the most complex one is making hardware and software high performance and, at the same time, render the system versatile enough to support as many workloads as possible. This paper provides a high level overview of the design and implementation process of such an Appliance architecture, as realized by the IBM PowerEN team. The Platform includes new silicon (the PowerEN processor), a novel system level board (Chroma card), system software and development kit, as well as end user applications for different industry domains. The solution has been completely designed by the team, starting from concept, to architecture, to implementation and delivery. The paper describes the most important characteristics of the Platform, detailing how these influence its capability of supporting multiple optimized workloads.
