A high-speed ring topology. In one embodiment, two base chip types are
required: a "drawing" chip, LoopDraw, and an "interface" chip,
LoopInterface. Each of these chips have a set of pins that supports an
identical high speed point to point unidirectional input and output ring
interconnect interface: the LoopLink. The LoopDraw chip uses additional
pins to connect to several standard memories that form a high bandwidth
local memory sub-system. The LoopInterface chip uses additional pins to
support a high speed host computer host interface, at least one video
output interface, and possibly also additional non-local interconnects to
other LoopInterface chip(s).
