Energy-efficient wireless network-on-chip architecture with log-periodic on-chip antennas

Abstract

On-chip wireless interconnects have emerged as a promising alternative to conventional wireline interconnects in Network-onChip (NoC) fabrics for multicore systems. However, it is not practical in the immediate future to arbitrarily scale up the number of wireless links without innovations in the physical layer. Here, we explore the design of a directional on-chip antenna based on a log-periodic structure. In this paper we propose the design of a wireless NoC (WiNoC) architecture with concurrent wireless links using these directional on-chip antennas. Through cycle accurate simulations we demonstrate that this novel WiNoC architecture attains better performance and energy efficiency compared to the state-of-the-art token based WiNoC of similar topology.

Design of a Wideband Antenna for Wireless Network-On-Chip in Multimedia Applications

“…The area is about 1.4 mm 2 , but this value does not include the feeding network, which instead is included in the area values of the other antennas considered in Table 2. It is worth noting that the performance of the PLPA in [82][83][84] at 60 GHz, in terms of bandwidth, gain and HPBW, is lower than the design proposed in this work.…”

“…[82][83][84]. The authors of [82][83][84] propose the design of an on-chip PLPA with a bandwidth of about 10% of the central frequency, e.g., 6 GHz of bandwidth around a central frequency of 60 GHz and featuring end-fire directivity.…”

“…The authors of [82][83][84] propose the design of an on-chip PLPA with a bandwidth of about 10% of the central frequency, e.g., 6 GHz of bandwidth around a central frequency of 60 GHz and featuring end-fire directivity. It is to be noted that the PLPA in [82][83][84] can also resonate at other frequencies, e.g., 44 GHz. From CAD simulations, the HPBW of the PLPA is 33 • along the end-fire direction, whereas the HPBW along the elevation is 30 • .…”

Intra-Chip and Inter-Chip Wireless Communication Analysis for Millimeter Wave using Miniaturized On-Chip Antenna

“…Congestion related to signal transmission between ICs can be decreased [1]. Bow-tie antennas are widely used for Ground Penetrating Radar System applications, as they possess a set of stringent antenna performances such as a low frequency of operation, ultra-wideband performances, minimal ringing, compaction, planar structure and light weight [12], [13]. Planar log periodic antenna was first introduced in wideband antenna design.…”
