resources: a local-bus resource (the middle bus) and two express-bus resources. Bus resources
are connected via repeaters. Each repeater has connections to two adjacent local-bus segments
and two express-bus segments. Each local-bus segment spans four cells and connects to con-
secutive repeaters. Each express-bus segment spans eight cells and bypasses a repeater.
Repeaters regenerate signals and can connect any bus to any other bus (all pathways are legal)
on the same plane. Although not shown, a local bus can bypass a repeater via a programmable
pass gate, allowing long on-chip tri-state buses to be created. Local/local turns are implemented
through pass gates in the cell-bus interface. Express/express turns are implemented through
separate pass gates distributed throughout the array.
