Modular Repeater Design
The expansion port of the bIMR chip also allows for
modular expansion. By sharing the arbitration duties be-
tween a backplane bus architecture and several sepa-
rate repeater modules one can build an expandable
repeater based on modular ‘plug-in’ cards. Each repeat-
er module performs the local arbitration function for the
bIMR devices on that module, and provides signals to
the backplane for use by a global arbiter.
