Abstract
A display system and method of displaying data relating to a generator control unit for an aircraft having a first memory of a first type and a second memory of a second type. The first memory contains display data relating to a generator control unit for an aircraft and a plurality of file markers interspersed among the display data, with each of the file markers occupying a respective position in the first memory. The first memory is searched to locate the positions of the file markers. Those positions are stored in the second memory, which is preferably a random-access semiconductor memory. The display data in the first memory is displayed by retrieving a portion of the display data from the first memory based upon the positions stored in the second memory.
Claims15
A method of displaying data comprising the steps of:
- searching a portion of a first memory containing display data and a plurality of file markers of first, second, third and fourth types interspersed among said display data at a plurality of positions to locate a plurality of said positions of a plurality of said file markers, said first type file marker indicating a beginning of a portion of said display data, said second type file marker indicating an end of a line of display data, said third type file marker indicating an end of a subportion of said display data, and said fourth type file marker indicating an end of the portion of said display data;
- storing position data relating to said plurality of said positions of said plurality of said file markers in a second memory, said second memory being of a different type than said first memory, said second memory comprising a random-access semiconductor memory, said storing position data step comprising;
- generating a first memory table containing position data related to said first type file markers, and
- generating a second memory table containing position data related to said third type file markers;
- retrieving a subportion of said display data from said first memory based upon said position data stored in said storing step;
- and
- displaying said subportion of display data retrieved in said retrieving step on a visual display.
A display system for displaying data comprising:
- a first memory containing display data and a plurality of file markers of first, second, third and fourth types interspersed among said display data, each of said file markers occupying a respective position in said first memory, said first type file marker indicating a beginning of a portion of said display data, said second type file marker indicating an end of a line of display data, said third type file marker indicating an end of a subportion of said display data, and said fourth type file marker indicating an end of the portion of said display data;
- means for searching said first memory to locate a plurality of said positions of a plurality of said file markers in said first memory;
- a second memory of a different type than said first memory and comprising a random-access semiconductor memory;
- means for storing position data relating to said plurality of said positions of said plurality of said file markers in said second memory, said position data storing means generating a first memory table containing position data related to said first type file markers and generating a second memory table containing position data related to said third type file markers;
- means for retrieving a subportion of said display data from said first memory based upon said position data;
- and
- means for displaying said subportion of display data retrieved by said retrieving means on a visual display.
