Abstract:

Method for efficient image distribution and management Invention employs compact image data structures and packet delivery techniques for Internet applications. Images on a Web page are inefficiently stored, using a single image per file. Invention uses clustering to merge similar images into a single file in order to exploit the redundancy between images. A 30-50% image data size reduction is achieved by eliminating the redundancies of color indexes. A metadata file permits an easy extraction of images. Present invention permits a more efficient use of the cache, since a shorter list of cache references is required. Packet and transmission delays are reduced by 50% eliminating redundant TCP/IP headers and connection time. Present invention eliminates redundancy and provides valuable benefits for optimizing packet delivery in IP networks by reducing latency and minimizing the bandwidth requirements.

Abstract:

A practical, low-energy consumption method of performing an N-point fast rier transform employing mathematically justified manipulation of input data, multirate, parallel and asynchronous circuit techniques. The multirate feature allows an input data sequence to be broken down into its polyphase components. The polyphase components can then be operated upon in a local and parallel manner. Localizing and minimizing loads of a circuit allows operations to be performed only when necessary in an asynchronous manner. The energy consumed in performing an N-point fast Fourier transform of the present invention is less than half that of known systems employing global memory and clocked methodologies. The feature of low energy consumption makes the invention attractive for use in hand-held audio/video devices where energy requirements can be met with a low rate of battery replacement.
