Method for operating a graphics card uses a graphics memory, independent graphics functions on a graphics processor not supporting graphics memory functions, a graphics card linking a display to a computer and an interface bus.

摘要

A graphics processor's control signals for access to a graphics memory are converted into control signal sequences for triggering graphics functions in a graphics memory, in which access to one or more reserved memory areas for virtual address space in a graphics processor is decoded. During access to this reserved area control signal sequences are generated. A graphics card uses an address decoder, a status switch and additional logic with a multiplexer.
