Abstract
Abstract An electronic computer system having a main functional unit and a plurality of sub-functional units, such as a memory unit, a function generator unit, etc., with all of the functional units being supplied with a key code signal from a single keyboard unit through a common key code bus line. All of the functional units give instruction signals to an arithmetic unit through a common instruction bus line.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
227 words
An electronic computer system comprising: A. a plurality of functional units, at least one of the functional units having means for generating an instructional signal; B. a keyboard unit for generatIng a key code signal including an information signal for selecting one of the functional units; C. a common key code bus line for receiving the key code signal from the keyboard unit and for distributing the same to each of the functional units; D. key code interpretation means included in each of the functional units for receiving and interpreting the key code signal; E. separate key code suppression signal generating means included in each of the functional units, the key code suppression signal generating means of one of the functional units generating a key code suppression signal to be distributed to the other functional units when said one functional unit is selected to receive a succeeding key code signal in accordance with the interpretation of the key code signal by the key code interpretation means of said one functional unit; and F. a key code suppression bus line connected in common to each of the key code suppression signal generating means for receiving the key code suppression signal from the one functional unit and for supplying the same to the rest of the functional units to bar them from operatively receiving the succeeding key code signal.
Claim 2
Dependent Claim
227 words
An electronic computer system comprising: A. a plurality of functional units, at least one of the functional units having means for generating an instructional signal; B. a keyboard unit for generatIng a key code signal including an information signal for selecting one of the functional units; C. a common key code bus line for receiving the key code signal from the keyboard unit and for distributing the same to each of the functional units; D. key code interpretation means included in each of the functional units for receiving and interpreting the key code signal; E. separate key code suppression signal generating means included in each of the functional units, the key code suppression signal generating means of one of the functional units generating a key code suppression signal to be distributed to the other functional units when said one functional unit is selected to receive a succeeding key code signal in accordance with the interpretation of the key code signal by the key code interpretation means of said one functional unit; and F. a key code suppression bus line connected in common to each of the key code suppression signal generating means for receiving the key code suppression signal from the one functional unit and for supplying the same to the rest of the functional units to bar them from operatively receiving the succeeding key code signal.
Claim 3
Dependent Claim
34 words
An electronic computer system as recited in claim 1; wherein one of the plurality of functional units is a main functional unit and another of the plurality of functional units is a memory unit.
Claim 4
Dependent Claim
27 words
An electronic computer system as recited in claim 1; wherein the plurality of functional units are made in the form of integrated circuits on separate semiconductor wafers.
Claim 5
Dependent Claim
107 words
An electronic computer system as recited in claim 1; wherein the system further comprises: A. an arithmetic unit; B. a common instruction bus line connected between the arithmetic unit and each of the functional units for receiving an instruction signal from the one of the functional units and for supplying the same to the arithmetic unit so that an arithmetic operation is performed therein; and C. instruction suppression signal generating means included in each of the functional units, the instruction suppression signal generating means of the one of the functional units generating an instruction suppression signal which prevents the other functional units from generating another instruction signal.
Claim 6
Dependent Claim
34 words

An electronic computer system as recited in claim 4; wherein the system further comprises: means in at least the one functional unit for generating a data signal, a common data bus line connected beween the arithmetic unit and each of the functional units for giving and taking a data signal between the arithmetic unit and the one of the functional units.
Claim 8
Dependent Claim
26 words
An electronic computer system as recited in claim 4; wherein the plurality of functional units are respectively made in integrated circuit form on separate semiconductor wafers.
