Explain how the VMEbus implements arbitration.
What will be an ideal response?
The figure below illustrates the structure of the VMEbus. Bus masters can be plugged in to the slots on the
bus,except for slot 1 that contains the arbiter. When a device in a slot wants the bus, it asserts a bus request BR0*
to BR3*. These are prioritized (but the actual prioritization is a user?defined feature).
The arbiter in slot 0 receives a request for the bus and chooses the winner if there are competing requests. It
sends out a bus grant which ripples along the bus using a daisy?chained arrangement (i.e., if a slot did not request
the bus, it passes the acknowledge on). If it requested the bus, it does not pass the message on. The device
receiving the acknowledge at the same level as its request, takes control of the bus by asserting bus busy, BBSY*.
