%X IC2IC links introduce blocking functionality to a low
latency high performance data link between independent
processors. The blocking functionality was achieved with the
so\-called alternating bit protocol. Furthermore, the
protocol hardens the link against message loss and message
duplication. This paper provides a detailed discussion of
the link signals and the protocol layer. The practical part
shows an example implementation of the IC2IC serial link.
This example implementation establishes an IC2IC link
between two configurable hardware devices. Each device
incorporates a process network which implements the IC2IC
transceiver functionality. This example implementation
helped us to explore the practical properties of the IC2IC
serial interconnect. First, we verified the
blocking capability of the link and second we analysed
different reset conditions, such as disconnect and
