Why does a video controller have its own processor and memory?


Producing high-resolution graphics in general, and motion video and simulated 3-D in particular, require considerable processing power and updating the display in real timerequires an efficient I/O and memory pathway. In addition, most graphics are generated by application programs using standardized graphics interface languages, such as Direct3D and OpenGL. A video controller is essentially a special-purpose computer dedicated to processing OpenGL or Direct3D commands to generate output to a display device. Like any other computer, it needs a CPU to process instructions and primary storage to hold program instructions and data.
