Abstract
In a computer system, a direct access, independently arbitrated video bus (connected to a personal computer (PC) -compatible video subsystem) is directly coupled to one or more dual-ported processors to eliminate video cycle traffic over the system bus or buses and I/O bus, thereby improving system performance. The preferred embodiment architecture has, in addition to the video bus, multiple processors coupled to at least two independently arbitrated system buses which are coupled to at least two independently arbitrated input/output (I/O) buses, to provide for rapid bus information signal transfer rates.
