Name of sponsoring Professor: Emma E. Regentova
Department: Electrical and Computer Engineering
Research: ONoC architectures
Mr. Lei Zhang, PhD student
The new ONoC proposed is based on the traditional electrical 2D-torus
but combined with optical components. By utilizing new optical devices
such as on-chip laser and wavelength routed resonator, data transmission
between cores in the new ONoC is through optical fiber can attaine the
speed of 10-40Gb/s. However, the improvement of the throughput of the
whole network is not simply linear to the core data transmission speed
between cores. It depends on many other factors such as routing algorithm,
buffer size and so forth.
In the simulation, the ONoC is set to be a structure similar to 2D torus
with n-by-m cores. Each core in the network will generate data packages
to a random destination core according to the Poisson distribution. Each
package will arrive to the destination core according to the routing algorithms.
Each core has a given number of channels. Data package entered to each
core is queued and directed to the corresponding channel according to
the destination. For the simplest simulation, the routing algorithm will
be the basic X-Y routing.
In addition, the new ONoC we proposed is extendable. By modifying the
structure of the optical-electrical router in the cores, different topologies
are generated. Thee performance of the new networks should be evaluated
by simulation.
