Abstract
A multi-window display station having main frame (host) interactive and local personal computer display data buffers is provided. The outputs of the two data buffers are merged, using a row or swath buffer, according to default or escape codes stored in one of the data buffers and the combined output drives a plasma panel display. Registers for modified data tags and for presence/absence of escape codes speed the panel update process. Means are included to provide alpha-numeric and graphic windows together on the panel screen.
Claims9
A display system for providing image determining data from plural sources to a display device wherein one of the sources provides control codes signifying display screen locations at which data from the other source is to be utilized,
- comprising a buffer for receiving and storing data from said one source for a display on the screen of said display device, memory means arranged in operation to store indications of the existence and positions of said control codes in said data corresponding to positions of control codes in said buffer,
- and means arranged in operation for receiving and overwriting in said buffer data from the other said source, the writing being under control of said indications in said memory means.
A data display system having a display device and plural sources of display data accessible in a manner comparable with the generation of a display on the display device under partial control of the contents of a primary one of the sources in that, when that source outputs a control code instead of a data code, the data for the corresponding area of the display is accessed from the other source characterized in that:
- (a) the display device is a storage-type display device in which the display is generated in swaths
- (b) a swath buffer interfacing the display data sources and the display device
- (c) a mask register arranged in operation to store indications of the existence and positions of said control codes in said data corresponding to positions of said control codes in said buffer, and
- (d) a control arranged in operation to load the swath buffer from the primary source, entering a counterpart mask element into the mask register per data or control code element for that swath and, thereafter, to cause the swath register to be overwritten where it contains control codes, under the control of the mask register content from the indicated other source.
