Abstract

See full text

A bubble domain chip is designed to provide the components necessary to perform all essential data-base functions. Many cross-linked loops in parallel allow the interchange of distinct columns of information. The use of an on-chip decoder achieves effective interchangeability of distinct rows of information. Thus, the basic storage structure and access modes conform to the high-level view of data implied by the relational data model, resulting in simpler programming. In addition, a plurality of comparators are provided to the plurality of storage loops to perform context search simultaneously on all the loops. The simultaneous search and the restriction to output of only qualified data greatly reduces the query time.
