Abstract
Abstract A true object generation system for true object generation in a video display generator or video display generator which comprises means for storage of data representative of an object run length and pel value and means responsive to the object run length data for holding the pel value at the storage means output for a time proportional to the object run length. True objects may be generated by either a run length or bit mapped code structure.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
114 words
A true object generation system, capable of operation in a run length or bit mapped mode, for true object generation in a video display generator comprising: shift register means, coupled to a source of data, for selectively receiving therefrom (a) bit mapped data and (b) object run length and pel value data; first means, coupled to said shift register means and responsive to said object run length data for holding said pel value at said shift register means output for a time proportional to said object run length; and second means, coupled to said shift register means, for switching said true object generation system between said bit mapped mode and said run length mode.
Claim 2
Dependent Claim
114 words
A true object generation system, capable of operation in a run length or bit mapped mode, for true object generation in a video display generator comprising: shift register means, coupled to a source of data, for selectively receiving therefrom (a) bit mapped data and (b) object run length and pel value data; first means, coupled to said shift register means and responsive to said object run length data for holding said pel value at said shift register means output for a time proportional to said object run length; and second means, coupled to said shift register means, for switching said true object generation system between said bit mapped mode and said run length mode.
Claim 3
Dependent Claim
24 words
The true object generation system of claim 1 wherein said shift register means operates in response to a shift/hold signal from said first means.
Claim 4
Dependent Claim
24 words
The true object generation system of claim 1 wherein said first means comprises a counter set in response to said object run length data.
Claim 5
Dependent Claim
19 words
The true object generation system of claim 3 wherein said counter comprises a multiplexer coupled to a shift register.
Claim 6
Dependent Claim
28 words
The true object generation system of claim 1 further comprising a multiplexer, coupled to said shift register means, for receiving said object run length and pel value data.
Claim 7
Dependent Claim
23 words
The true object generation system of claim 5 further comprising a latch, coupled to said multiplexer, for holding an output from said multiplexer.
Claim 8
Dependent Claim
164 words
A true object generation system, capable of operation in a run length or bit mapped mode, for true object generation in a video display generator comprising: a first shift register, coupled to a source of data, for selectively receiving therefrom (a) bit mapped data and (b) object run length and pel value data; first means, coupled to said first shift register and responsive to said object run length data for establishing a count value proportional to said object run length; second means, coupled to and responsive to said first means, for decrementing from said count value, said second means coupled to said first shift register for applying a hold signal to said first shift register during a countdown from said count value and for applying a shift signal to said first shift register when said countdown is complete; and third means, coupled to said first shift register, for switching said true object generation system between said bit mapped mode and said run length mode.
Claim 9
Dependent Claim
164 words
A true object generation system, capable of operation in a run length or bit mapped mode, for true object generation in a video display generator comprising: a first shift register, coupled to a source of data, for selectively receiving therefrom (a) bit mapped data and (b) object run length and pel value data; first means, coupled to said first shift register and responsive to said object run length data for establishing a count value proportional to said object run length; second means, coupled to and responsive to said first means, for decrementing from said count value, said second means coupled to said first shift register for applying a hold signal to said first shift register during a countdown from said count value and for applying a shift signal to said first shift register when said countdown is complete; and third means, coupled to said first shift register, for switching said true object generation system between said bit mapped mode and said run length mode.
Claim 10
Dependent Claim
17 words
The true object generation system of claim 7 wherein said first means comprises a run length multiplexer.
Claim 11
Dependent Claim
17 words
The true object generation system of claim 7 wherein said second means comprises a second shift register.
Claim 12
Dependent Claim
22 words
The true object generation system of claim 7 further comprising a multiplexer for receiving said object run length and pel value data.
Claim 13
Dependent Claim
23 words
The true object generation system of claim 10 further comprising a latch, coupled to said multiplexer, for holding an output from said multiplexer.
