Network Topologies:Multistage Omega Network

Each stage of the Omega network implements a perfect shuffle as follows: 000 001 010 011 100 101 110 111 A perfect shuffle interconnection for eight inputs and outputs.

= left_rotate(000)= left_rotate(100)= left_rotate(001)= left_rotate(101)= left_rotate(010)= left_rotate(110)= left_rotate(011)= left_rotate(111)
