Abstract

Associative processing is enhanced by encoding the binary or other data signals into a higher level code such as hexadecimal, decimal, etc., performing the associative processing, and then decoding the high-level coded output of the associative processing back to binary or other data coding.

Associative Processor

Associative processing is enhanced by encoding the binary or other data signals into a higher level code such as hexadecimal, decimal, etc., performing the associative processing, and then decoding the high-level coded output of the associative processing back to binary or other data coding.

A first argument, A, is supplied to an encoder to a search match (AND) array. The encoder activates the match array. A second argument, B, Is supplied to the other inputs of the array for initiating a match function, as is well known in associative processing. The outputs of the match array are all supplied to the output or read array; a usually logic OR or summing associative function. Argument C is applied to one set of inputs to the output array, to select which of the outputs from the match array are to be utilized as output signals. One or a plurality of such output signals drive the decoder, which converts the output function indicating signals to binary or other data processing coded signals. An exemplary form of the decoder may be an exclusive OR, wherein the inputs to the exclusive OR are from opposite halves of the output array; that is, the output array can be logically divided into two or more portions, each associated with a different group of logic functions. The outputs of the various portions are then combined in exclusive OR, AND, majority decision element, or the like, for conversion into the data-processing code.
