Network-on-Chip (NoC) is an emerging paradigm for communications within large VLSI systems implemented on a single silicon chip. However, the electronic network on chip design faces many problems like energy consumption, bandwidth and QoS. Compared with traditional electronic NoC, optical Network on Chip exhibits advantages of high-bandwidth, low latency and power dissipation. In this paper, a ...

The design of appropriate communication architectures for complex Systems-on-Chip (SoC) is a challenging task. One promising alternative to solve these problems are Networks-on-Chip (NoCs). Recently, the application of deterministic and stochastic Petri-Nets (DSPNs) to model on-chip communication has been proven to be an attractive method to evaluate and explore different communication aspects....

We propose 3D mesh-based optical network-onchip (ONoC) based on a novel low-cost 6x6 optical router, and quantitatively analyze thermal effects on the 3D ONoC. Evaluation results show that with the traditional thermal tuning technique using microheater, the average power efficiency of the 3D ONoC is about 2.7pJ/bit, while chip temperature varies spatially between 55C and 85C. In comparison, a n...

For the first time, the 4- and 5-port optical routers are designed by using the West First routing algorithm for use in optical network on chip. The use of the WF algorithm has made the designed routers to provide non-blocking routing in photonic network on chip. These routers not only are based on high speed Mach-Zehnder switches(Which have a higher bandwidth and more thermal tolerance than mi...

Systems-on-Chip architecture integrates several heterogeneous components on a single chip.

as wireless networks with high data rate get widely deployed, improving the performance of tcp over these networks plays vital role. wireless link losses have dramatic adverse impact on tcp performance due to the difficulty in distinguishing the congestion losses from wireless link losses. we first, studied the various existing bandwidth estimation algorithms over the wireless networks. in this...

Networks on Chips (NoCs) are required to tackle the increasing delay and poor scalability issues of bus-based communication architectures. Many of today’s NoC designs are based on single path routing. By utilizing multiple paths for routing, congestion in the network is reduced significantly, which translates to improved network performance or reduced network bandwidth requirements and power co...

Heat balance is of critical importance on the design of network-on-chip (NoC). In a 3D topology NoC, routing algorithm should take considerations of each layer’s peak temperature and traffic to prolong chip’s service life. In this paper, we propose a heat-balanced, deadlock-free routing algorithm named Direct Ratio Transport Layer (DRTL). DRTL distributes and arranges traffics according to the ...

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 ca...
