Abstract
Abstract Large scale integration techniques are combined with holographic techniques to provide a highly compact data processing system of extreme high speeds of operation. A single integrated circuit control module containing light responsive devices is selectively actuated by different patterns of light beams generated by appropriate holograms each selected from a single holoarray to provide all of the arithmetic and logic functions of a data processing system.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
132 words
In a data processing system having program storage facilities for storing a program and arithmetic, logic and addressing instrumentalities controlled thereby for performing arithmetic and logic functions; a control module comprising activatable logic circuits interconnecting said instrumentalities, each of said logic circuits including a light responsive device for activating said circuits; a source generating a coherent beam of light, said source being controllable to provide a plurality of different beam orientations; a holoarray responsive to said beam for generating light control patterns and directing said patterns to impinge upon the light responsive devices to activate said logic circuits; and decoding means responsive to said addressing instrumentalities for controlling said source to provide said different beam orientations thereby providing the different control patterns necessary to the performance of said arithmetic and logic functions.
Claim 2
Dependent Claim
132 words
In a data processing system having program storage facilities for storing a program and arithmetic, logic and addressing instrumentalities controlled thereby for performing arithmetic and logic functions; a control module comprising activatable logic circuits interconnecting said instrumentalities, each of said logic circuits including a light responsive device for activating said circuits; a source generating a coherent beam of light, said source being controllable to provide a plurality of different beam orientations; a holoarray responsive to said beam for generating light control patterns and directing said patterns to impinge upon the light responsive devices to activate said logic circuits; and decoding means responsive to said addressing instrumentalities for controlling said source to provide said different beam orientations thereby providing the different control patterns necessary to the performance of said arithmetic and logic functions.
Claim 3
Dependent Claim
34 words
A system as in claim 1 in which said holoarray is constituted of a plurality of holograms each generating a unique light control pattern in response to a unique orientation of said light beam.
Claim 4
Dependent Claim
58 words
A system as in claim 2 in which said logic circuits include circuits to perform specific functions, each circuit having inputs responsive to signals representing data, an output, and the light responsive device being interposed between said inputs and the output, the latter providing an output signal in response to impinging light derived from said light control patterns.
Claim 5
Dependent Claim
22 words
A system as in claim 3 in which selected circuits of said logic circuits are adapted to perform And and Or functions.
Claim 6
Dependent Claim
28 words
A system as in claim 3 further including bistable circuits conditioned by light responsive devices adapted to perform reset functions in response to an appropriate light control pattern.
Claim 7
Dependent Claim
23 words
A system as in claim 3 in which said control module is comprised of a matrix of integrated elements constituting said logic circuits.
Claim 8
Dependent Claim
45 words
A system as in claim 6 in which the integrated logic circuits are interconnected to form different registers to accommodate said data and instructions, said registers being oriented in accordance with a coordinate frame of reference specifying columnar and zone locations in said control module.
Claim 9
Dependent Claim
36 words
A system as in claim 7 in which said holoarray is disposed in spaced relationship with said control module and the coordinate dimensions of the former are less than the corresponding dimensions of said control module.
Claim 10
Dependent Claim
38 words
A system as in claim 8 in which said holograms are so oriented that any designated activatable logic circuit may be influenced by a corresponding light ray in any of the light control patterns generated by said holograms.
