Network-on-chip (NoC) is currently the chosen paradigm for interconnection in multicore architectures. On the other hand, the development of these architectures with thousands of cores leads to several issues regarding latency and power consumption, especially with conventional wired interconnects. Moreover, they do not support specific features like broadcast and multicast. Radio-Frequency NoC based on OFDMA seems an appropriate solution to overcome such issues, providing low latency for long communications and a significant communication bandwidth with a high spectral efficiency. It also permits a dynamic allocation of the available bandwidth among the different elements of the NoC, according to the communication needs. The routing algorithm has a significant impact on the overall performance of a RF-NoC, by diffusing the traffic in a suitable way between the wired and the wireless paths in order to improve the throughput and reduce the latency. In this paper, a threshold-based routing algorithm is proposed and evaluated for a 32×32 RF-NoC OFDMA architecture with 32 concurrent wireless channels. We demonstrate the importance to finely tune the threshold parameter to achieve a certain level of performance. Simulation results show a significant improvement in terms of latency and throughput.

“…In another study [23], a 3D Torus ONoC along with an adaptive routing algorithm has been proposed for improving the performance of 3-D ONoCs. In [24], 3D-NoC, Photonic NoC and WiNoC have been compared. The study of these methods indicates that these approaches, given their unique characteristics, can solve the problems caused by scalability in NOC; however, they have some requirements for design and manufacturing which must be further investigated [5].…”

Proposing an optimal structure for the architecture of wireless networks on chip

The need for more scalability in design on one hand and the occurrence of latency and high power consumption in communications between distant cores on the other hand are considered as the most common challenges which networks on chip encounter. Today, wireless network on chip (WiNoC) is regarded as a novel proposed approach in which wireless links are shortcuts for the fast data transmission between distant cores. However, the presence of Wireless routers (WRs) in WiNoC increases the cost and area. Thus, finding an optimal structure for communicating between cores is essential. In this paper, genetic algorithm (GA) and simulated annealing (SA) are compared with each other under different traffic patterns to find the best positions of WRs. The results obtained from the simulations of this study indicate that GA has higher efficiency than SA. Furthermore, the resulting structure has fewer WRs and relatively desirable performance.

“…Instead, for the antenna, there are still open issues on optimizing the trade-off between area, gain and bandwidth. For example, the survey work [56] also declares that the on-chip antenna is still one of the most difficult components to integrate on-chip. Moreover, [56] declares that, although implementations of on-chip antennas have been proposed and studied in literature, there are still many challenges in manufacturing and integrating them in terms of area, performance, and energy overheads, especially as the number of on-chip cores will be scaling up in the future.…”

Abstract:To allow fast communication-at several Gb/s-of multimedia content among processors and memories in a multi-processor system-on-chip, a new approach is emerging in literature: Wireless Network-on-Chip (WiNoC). With reference to this scenario, this paper presents the design of the key element of the WiNoC: the antenna. Specifically, a bow-tie antenna is proposed, which operates at mm-waves and can be implemented on-chip using the top metal layer of a conventional silicon CMOS (Complementary Metal Oxide Semiconductor) technology. The antenna performance is discussed in the paper and is compared to the state-of-the-art, including the zig-zag antenna topology that is typically used in literature as a reference for WiNoC. The proposed bow-tie antenna design for WiNoC stands out for its good trade-off among bandwidth, gain, size and beamwidth vs. the state-of-the-art.
