Implementation of character string pattern matching on a multiprocessor

Abstract

An algorithm to do pattern matching, a basic character string operation, is presented. The Programmable Algorithm Machine (PAM), a proposed special-purpose computer which will feature multiple processing elements and operate efficiently over a wide class of applications, is described. It is shown that the multiple processing elements of the PAM allow concurrent execution of independent operations both in a special case of the pattern matching algorithm, where the string sizes (lengths) are known at compile time, and in the general case, where the sizes are not known.
