Crossbar network in computer architecture
WebIn all Cray multiprocessors, crossbar networks are used between the processors and memory banks. The banks use 64-, 128-, or 256-way of interleaving (in Cray Y-MP) that can be accessed via four ports. Multiport Memory One of the major drawbacks of a crossbar networks is its high cost and cumbersome wiring, when it is built in a multiprocessor. WebCrossbar is an example of this type of network. Rearrangeable non-blocking: This type of network can establish all possible connections between inputs and outputs by …
