Abstract

A processing circuit P1 for recognition and comparison of complex patterns in high-speed data streams can form a node in a network of circuits of this kind and comprises an interface for inputting of parameters for the circuit, at least one kernel processor P0 in the form of a comparator unit (COM) for comparing two data words, a logic unit (E) connected with the comparator unit and comprising a multiplexer (MUX1), a first D flip-flop (2), a latency unit (LAT) for delaying a positive binary value with a given number of time units, a second D flip-flop (4), a sequence control unit (SC) which monitors and controls a comparison operation in the comparator unit (COM), and a result selector (RS) which combines two result values from other processing circuits or other result selectors. A search processor circuit (PMC) for performing search and comparison operations on complex patterns comprises a multiprocessor unit Pn with processing circuits P1 in a tree structure and forms a binary or superbinary tree with n+1 levels S and degree k = 2m, m being a positive integer ≥ 1. An underlying level S¿n-q? generally comprises 2?mq¿ circuits P¿n-q? provided nested in the 2?m(q-1)¿ circuits P¿n-q+1? on the level Sn-q+1. A 0?th¿ level S¿0? defined for q = n in the unit Pn comprises 2?m(n-1) to 2mn¿ kernel processors P¿0? which form comparator units (COM) in the circuits P1. All circuits P1, P2...Pn have identical interfaces (I) and a logic unit (E) with a result selector (RS) for collecting the results of a search operation or a comparison operation. Use in search engines for search and retrieval of data stored in data bases.
