<p>A system and method for interfacing a video subsystem (110) capable of driving a video display monitor to a personal computer (PC) architecture. The system and method involves connecting the video subsystem (110) to a host bus (104) via a host bus video interface (402). The host bus (104) communicates directly to a central processing unit (CPU) (102) and to a slower system bus (138) through buffers (124, 128). The central processing unit (102) as well as a system bus master (108) connected to the system bus (138) can communicate at high speeds to the video subsystem (110). The host bus video interface (402) includes a fast temporary storage buffer (406) so that the CPU (102) or the system bus master (108), during a write cycle to the video subsystem (110), can write data at high speed to the video subsystem (110). The video subsystem (110) may further include SRAM in its video memory (422) to increase performance. <IMAGE></p> |
