19.6 OIN DESIGN DRIVER IMPLEMENTATION
CONSIDERATIONS
In this section, the implementation of an integrated 64 64 OIN design based on the
SPINet architecture is considered. The design driver is an EOM network with N

I/O terminals and a four-stage distribution network that will require N

Ref. [48], has an area of 1 mm
