发明名称 Universal graphic adapter for interfacing with UGA hardware via UGA virtual machine and means for abstracting details of the UGA hardware
摘要 The subject invention relates to a Universal Graphics Adapter (UGA) that is a hardware-independent design that encapsulates and abstracts low-level graphics hardware in a standard manner through firmware. UGA is a firmware standard, intended to wrap existing or planned hardware, including VGA. UGA does not require the use of real-mode assembly language, direct hardware register, or frame buffer access to program, thus providing advantages over conventional systems. UGA supports basic drawing operations, continuous display modes, and power management. As a firmware-based standard, UGA facilitates updating a system to support both evolving and new hardware features.
