Abstract:
1. A multi-user host computer system for supporting multiple active remote terminals each having their own physical input controls, comprising: a hardware graphics and display subsystem (GPU) having a host CPU means for connecting said graphics and display subsystem to said host CPU; means for connecting said multiple active remote terminals via a network to said host CPU; means for more than one of said virtual machines to asynchronously access said hardware graphics and display subsystem whereby address translation is performed between the CPU virtual machines and GPU display memory, between the GPU subsystem and the GPU display memory, and between the CPU virtual machines and GPU control registers; and means for managing the selective updates from said GPU display memory by the host CPU so that only the selective updates of said subframes will be transferred via a network subsystem to corresponding ones of said remote terminals.
