“…Emerging interconnect architectures tend to reduce performance limitations of multi-hop communication in conventional wired NoCs. Four emerging interconnects are explored to address the long-range multi-hop communication bottleneck [5]: three-dimensional (3D) [6], photonic [7], RF/wireless NoC [8]. The mm-wave based WiNoCs have emerged as one of the promising solutions for scalable, energy-efficient CMOS compatible technology.…”

Wireless Networks-on-Chip (WiNoC) are being explored for parallel applications to improve the performances by reducing the long distance/critical path communications. However, WiNoC still require precise propagation models to go beyond proof of concept and to demonstrate it can be considered as a realistic efficient alternative to wired NoC. In this paper, we present accurate 3D models based on measurements in Ka band and Electromagnetic (EM) simulations of transmission on silicon substrate in the V band and the Sub-THz band. Using these EM results, a time-domain simulation is performed using an On-Off Keying (OOK) modulation based transmission with different PA/LNA configurations. Our results highlight the type of performances and tradeoffs to be considered according to different parameters such as power output and amplifier's gain. By improving the knowledge about the signal propagation, one can conduct precise design space exploration for parallel applications. We discuss the realistic channel modeling and we present also hybrid solutions and associated limitations of WiNoC architectures. We conclude the paper with research directions to be explored to make WiNoC a reality.

“…Due to multiple reflections in the transmission channel, this technique leads to a deterioration of performance when the number of T x /R x increases. The second category considers an “indirect coupling” (eg, capacitive coupling Figure B); but it suffers from high reflection coefficients at T x /R x . These methods lead to an important loss of power during the transmission.…”

This paper presents a new radio frequency channel access method to a radio frequency (RF) interconnect for intra‐chip communications. The method overcomes the undesired effects that come from multiple connections in classical methods. It is based on an active access, through transistors associated in a distributed topology. This leads to better properties in terms of reflection and transmission coefficients along the transmission line. This approach is validated by making a deep comparison with the basic existing access methods (eg, direct and capacitive). Measurements on a test circuit using the 0.25 μm SiGe BiCMOS technology confirm the good performance of the proposed access.

International audience— This paper introduces flexible radio techniques inside integrated circuits in order to tackle the interconnect issue for many-core chips. We propose to take benefits from OFDMA for a RF-interconnect associated to a carrier allocation policy and adaptive modulation. A 20 GHz bandwidth is shared between 32 tilesets made of 32 tiles of 4 cores each, for a 4096 cores chip. We adopt a cognitive radio approach in order to dynamically share 1024 carriers, which avoids inter-cluster communication contention and decreases latency compared to conventional static approaches
