ABSTRACT:
A fully parallel, distributed logic associative processor, comprising a content-addressable memory having computational logic associated with each memory cell. The cells are arranged in a rectangular array, and logical operations may be performed between adjacent cells, or between the data being input to the machine, and the contents of a chosen word, or chosen words.
The type of logical operation may be chosen from the complete set of two-variable functions plus the single variable functions "transfer" and "invert". Several of the two-variable functions may be obtained by combining other two-variable functions with "invert". In some cases, single gates may perform both multiplexing and logical functions, or logical and storage functions.
Each store word is equipped with a response unit. This may be set during a match operation if a word matches the input word. During a match operation, all store words are searched simultaneously. Portions of the input word may be masked, and these bits are then not involved in the match operation. Instructions applied to the command inputs cause an operation to take place upon selected words. The selected words may comprise the entire store contents, all words with their response units set, or the first work in store with its response unit set. In the latter case, all words with the set response units may be processed consecutively. Otherwise the chosen data words will be processed simultaneously. The machine with a fixed number of output leads may have any desired number of words, and is particularly applicable to L.S.I. packaging.
The content addressable facility permits flexible and efficient addressing schemes to be used, and the word by word interrogation facility also makes the machine suitable for holding a program rather than data if required.
