The performance of router directly impacts the Network-on-Chip (NoC) performance. This paper focus on developing efficient microarchitecture of allocator in the router and proposed matrix-diagonal allocator with high matching quality and low packets latency. The allocator, taking advantage of the fact that each element in the diagonal doesn't share the same row or column, includes matrix-diagonal...
In the many-core era, the network on-chip (NoC) is playing a larger role in meeting performance, area and power goals, as router buffers contribute greatly to NoC area and power usage. Proposals have advocated bufferless NoCs, however a performance wall has been reached such that high throughput performance has not been extracted. We present SCEPTER, a high-performance bufferless mesh NoC that sets...
Networks-on-Chip (NoCs) offer a scalable means of on-chip communication for future many-core chips. This work explores NoC router microarchitectures which leverage traffic pattern biases and imbalances to reduce latency and improve throughput. It introduces STORM, a new, low-latency, fair, highth-roughput NoC router design, customized for the traffic seen in a two-dimensional mesh network employing...
IEEE 802.22 standard is the first worldwide standard using cognitive radio (CR) technology for wireless regional area networks (WRANs). Orthogonal frequency-division multiple access (OFDMA) is employed for point-to-multi-point (P2M) communication between base stations (BS) and customer premises equipments (CPEs) in WRANs. The large coverage of a single cell (up to 100 km of radius) is the unique feature...
On-chip router typically has buffers dedicated to its input or output ports for temporarily storing packets in case contention occurs on output physical channels. Buffers, unfortunately, consume significant portions of router area and power. While running a traffic trace, however, not all input ports of routers have incoming packets needed to be transferred at the same time. As a result, a large number...
The future Internet is envisioned to host a large number of virtual networks managed by different operators sharing the same physical infrastructure. In such a scenario, an operator may not even own physical resources as such, but lease virtual resources to have their own virtual networks. While control-plane virtualization with several routing instances becomes common in equipments, the data plane...
