Patent

CA 2146352

A non-numeric coprocessor for fuzzy information retrieval and pattern recognition has means for information processing and is con- nectable to a host computer and a data source. A plurality of internal processing elements are organized in a number of simultaneously op- erable window modules (W0, W1, ...) arranged for inspecting data streams from said source. The processing elements compare data stream bytes with predetermined upper and lower bounds, to decide whether a byte is within said bounds, and, if so, to produce a hit sig- nal. Each window module has a window match logic for correlating hit signals from its different processing elements, and to produce a window match signal by the occurence of a predefined match. By structuring the coprocessor in this manner, a parallel processing pot- ential is attained, which can be utilized by data routing means (12) to allow for separate data streams to be routed to individual or chained window modules selectably configured as groups of windows or su- per-windows according to application needs.
