This said, it is not completely clear when a “video chip” is a “video display controller” and when it is a “video display processor”. Input signal from the DMA controller acknowledging. Two byte refresh buffer memories are contained onchip. In addition to scan control and operating the character-generating ROM, the handles refresh, data transfer from main memory, limited graphics generation, cursor control, lightpen detection and other auxiliary functions.

Linux kernel mailing list. The requests DMA. Keyboard-display interface Intel have announced a new programmable single-chip k e y b o a r d – d i s play interface device, thefor use with general-purpose 8-bit microprocessors. For example, the TMS is sometimes called a “video display controller” and sometimes a “video display processor”.

The tasks are divided system memory, CRT controllerregister set, control and status words, and a flexible channel controller. IOPand keyboard scan and decode. Then IC for 3D rendering followed. No abstract text available Text: The may be used in either a keyboard or scanned display mode, or both simultaneously. Data is entered into an internal 16 X 8 display memory which can, if desired, be organized as 82275 16 X 4 display memories.
