Abstract:
A method and system for displaying graphics on a display of a second module remotely connected with a first module via a data communications medium. A first controller for the first module and a second controller for the second module are connected to first and second graphics processors, respectively, both graphics processors being operative to request data from the first module when ready to process data. The first controller interfaces between the first graphics processor and the first module. The second controller interfaces between the second graphics processor and the first module via the data communications medium and the first controller. The first controller duplicates data returned to the first graphics processor by the first module in response to data requests, and transmits the duplicated data to the second controller via the data communications medium. The second controller intercepts data requests made by the second graphics processor, correlates the intercepted requests with the duplicated data received from the first controller and transmits the duplicated data to the second graphics processor on a basis of this correlation. The second graphics processor uses the received duplicated data to generate graphics for display on the display of the second module.
