High performance, robustness, and energy-efficiency are crucial for the widespread adoption of such platforms. Networks-on-Chip (NoCs) have emerged as communication backbones to enable a high degree of integration in multicore Systems-on-Chip (SoCs). Despite their advantages, an important performance limitation in traditional NoCs arises from planar metal interconnect-based multihop links with high latency and power consumption. This limitation can be addressed by drawing inspiration from the evolution of natural complex networks, which offer great performance-cost trade-offs. Analogous with many natural complex systems, future multicore chips are expected to be hierarchical and heterogeneous in nature as well. In this article we undertake a detailed performance evaluation for hierarchical small-world NoC architectures where the long-range communications links are established through the millimeter-wave wireless communication channels. Through architecture-space exploration in conjunction with novel power-efficient on-chip wireless link design, we demonstrate that it is possible to improve performance of conventional NoC architectures significantly without incurring high area overhead.<\/jats:p>","DOI":"10.1145\/2287696.2287706","type":"journal-article","created":{"date-parts":[[2012,8,21]],"date-time":"2012-08-21T13:06:30Z","timestamp":1345554390000},"page":"1-25","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":93,"title":["Performance evaluation and design trade-offs for wireless network-on-chip architectures"],"prefix":"10.1145","volume":"8","author":[{"given":"Kevin","family":"Chang","sequence":"first","affiliation":[{"name":"Washington State University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sujay","family":"Deb","sequence":"additional","affiliation":[{"name":"Washington State University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Amlan","family":"Ganguly","sequence":"additional","affiliation":[{"name":"Rochester Institute of Technology"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xinmin","family":"Yu","sequence":"additional","affiliation":[{"name":"Washington State University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Suman Prasad","family":"Sah","sequence":"additional","affiliation":[{"name":"Washington State University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Partha Pratim","family":"Pande","sequence":"additional","affiliation":[{"name":"Washington State University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Benjamin","family":"Belzer","sequence":"additional","affiliation":[{"name":"Washington State University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Deukhyoun","family":"Heo","sequence":"additional","affiliation":[{"name":"Washington State University"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2012,8,15]]},"reference":[{"key":"e_1_2_1_1_1","unstructured":"AGILENT 2012.
