ABSTRACT:
Interfacing a video subsystem capable of driving a video display monitor to a personal computer (PC) architecture. The system and method involves connecting the video subsystem to a host bus via a host bus video interface. The host bus communicates directly to a central processing unit (CPU) and to a slower system bus through buffers. The central processing unit as well as a system bus master connected to the system bus can communicate at high speeds to the video subsystem. The host bus video interface includes a fast temporary storage buffer so that the CPU or the system bus master, during a write cycle to the video subsystem, can write data at high speed to the video subsystem. The video subsystem may further include SRAM in its video memory to increase performance.
