Interconnection Network Sun Fireplane

150 MHz Redundant 18×18 data, address and response flat

crossbar interconnect Flat crossbar provides uniform memory access

with an aggregate bandwidth of 172.8 GB / s

Crossbar Interconnect A network in which all input ports are directly connected to

all output ports without interference from messages from other ports. In a one-stage crossbar this has the effect that for instance all memory modules in a computer system are directly coupled to all CPUs. This is often the case in multi-CPU vector systems.

In multistage crossbar networks the output ports of one crossbar module are coupled with the input ports of other crossbar modules. In this way one is able to build networks that grow with logarithmic complexity, thus reducing the cost of a large network.
