WALSHSTORE: The Application of Burst Processing to Fail-Soft Storage Systems Using Walsh Transforms.

Abstract

WALSHSTORE is concerned with the investigation into the application of orthogonal transforms, e.g., Walsh transforms, to the storage of visual images in a fail-soft manner, i.e., the system can sustain losses but the retrieved image can still be recognized, even if in a degraded form. The application of Burst Processing to various parts in such a system is investigated together with an analysis of the amount of storage and speed of computation that can be achieved. This paper presents the necessary theory and the implementation of the Walsh transformers and the fail-soft storage which were constructed and tested. Additionally, some software simulation results are compared to the actual machine performance. (Author)
