Press Release
OCP-IP Releases Survey of Network-on-Chip
Architectures
BEAVERTON, Ore. — May 13, 2008 — OCP-IP today announced the availability
of a white paper discussing a survey of Network-on-chip (NoC) proposals.
NoCs replace dedicated, design-specific wires with scalable, general
purpose, multi-hop networks. NoCs can provide separation between computation
and communications, serve as a platform for test, and support IP reuse,
increasing engineering productivity and decreasing time to market. This
paper gives an overview of the state-of-the-art network-on-chip
proposals.
The survey contains sections on NoC Architecture Comparison, Comparison
Criteria, NoC Evaluation Methods, and NoC Router Implementation. NoC
Architecture Comparison discusses switching policy, topology, routing,
quality-of-service, as well as testing and fault tolerance. NoC Evaluation
Methods covers evaluation metrics and example test cases. Router
Implementation discusses router parameters, minimum latency, area and
operating frequency.
This paper cites numerous examples from literature selected to highlight
the contemporary approaches and reported implementation results.

Work on the survey of NoCs paper was completed by Tampere University of
Technology and the OCP-IP NoC Benchmarking Group. For the latest up-to-date
information on the work of this group please see the OCP-IP Newsletter at:
