This handbook summarizes four cpu-months of system simulation, allowing the consequences of different design decisions to be compared. It explains the principles of the new generation of small-scale low-buffer serial interconnects. Using the specific example of IEEE 1355 - 1995 links and the STC104 high-valancy switch chip the book shows how this technology can provide modular, fault-tolerant and scalable interconnect. The picture is rounded out with descriptions of network topologies, case studies and many practical tips.
