Implementation
•Designed
by Kevin Bolding
•Degree
4, suitable for mesh and torus routing
•20
phit frames, 16 bit phits, 5 frame multi-queue
•Linear-feedback
shift register for random numbers
•Unidirectional
channels with alternating opportunity at the end of each packet
•Separate
injection and delivery channels
•Node
latency is 4 ticks with 15 ns clock
•Technology
is 1.2 m CMOS, with scalable design
rules
•Comparable to the Elko router, an oblivious router designed at
Caltech using the same technology
