Abstract
Abstract Digital data storage register modules for a of the type that can include one or more functional characters of the type that include an input bus, an output bus, control signal input means and which can have inputs and outputs that can be connected to similar or other characters for modular expansion of the operational capabilities. The functional characters including: a modular register character which provides storage for operands of a micro-program; a general logic character that performs basic logic functions for use by the micro-program; an arithmetic logic character that provides major arithmetic functions for use by the micro-program; an input/output character that provides input/output interface to the micro-program machine; a micromemory counter character that provides micromemory address registers and related functions; a micro-instruction register that contains the micromemory word registers; and a micro-array character that contains a micromemory array.

Claim 1
Independent Claim
195 words
In a modular digital storage circuit arrangement, an individual modular unit providing for concurrent random selection of storage locations, said unit comprising: a plurality of parallel input busses, each of said busses supplying in parallel an individual data byte; a plurality of data registers for storing the data bytes supplied by said input busses; gating circuit means for selectively and concurrently coupling individual ones of said registers to individual ones of said input busses; and control means, individual to said modular unit, for generating control signals for controlling said gating circuit means, said control means including a plurality of decoders, wherein each of said decoders (a) is individual to an assigned one of said input busses, (b) has inputs for receiving address signals designating both said individual modular unit and any selected one of said data registers within said unit, and (c) supplies to said gating circuit means in response to received ones of said address signals those of said control signals that relate to said assigned input bus, whereby respective data bytes supplied by respective ones of said input busses may be concurrently and selectively stored in respectively addressed registers of said modular unit.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
191 words
The individual modular unit of claim 1, further comprising: a plurality of parallel output busses, each of said output busses capable of outputting in parallel a data byte from a selected one of said plurality of data registers; output gating circuit means for selectively and concurrently coupling individual one of said registers to individual ones of said output busses; and output control means, individual to said modular unit, for gEnerating control signals for controlling said output gating circuit means, said outut control means including a plurality of output decoders, wherein each of said output decoders (a) is individual to an assigned one said plurality of output busses (b) has inputs for receiving output address signals designating both said individual modular unit and any selected one of said data registers within said unit, and (c) supplies to said output gating circuit means in response to received ones of said output address signals, those of said output control signals that relate to said assigned output bus, whereby respective data bytes stored in respectively addressed registers of said modular unit may be output by respective ones of said output data busses selectively and concurrently.
Claim 4
Dependent Claim
201 words
In a modular digital storage circuit arrangement, an individual modular unit providing for concurrent random access of storage locations, said unit comprising: a plurality of parallel output busses, each of said busses outputting in parallel an individual data byte; a plurality of data registers for storing the data bytes to be output by said output busses; gating circuit means for selectively and concurrently coupling individual ones of said registers to individual ones of said output busses; and control means, individual to said modular unit, for generating control signals for controlling said gating circuit means, said control means including a plurality of decoders wherein each of said decoders (a) is individual to an assigned one of said output busses, (b) has inputs for receiving address signals designating both said individual modular unit and any selected one of said data registers within said unit, and (c) supplies to said gating circuit means in response to received ones of said address signals those of said control signals that relate to said assigned output bus, whereby respective data bytes stored in respectively addressed ones of said data registers of said modular unit may be concurrently and selectively output by respective ones of said output busses.
