Network operation and management is a primary role of network operations center (NOC) which provides critical services for telecommunication networks, enterprise networks, campus networks, etc. Regarding hybrid research networks based on traditional IP production network and dedicated lightpath provisioning network, additional functionalities to traditional NOC facilities are required to provid...

Looking into the future, when the billion transitor ASICs will become reality, this paper presents Network on a chip (NOC) concept and its associated methodology as solution to the design productivity problem. NOC is a network of computational, storage and I/O resources, interconnected by a network of switches. Resources communcate with each other using addressed data packets routed to their de...

This article presents an overview of the design process of an interconnection network, using the technology proposed by Arteris. Section 2 summarizes the various features a NoC is required to implement to be integrated in modern SoCs. Section 3 describes the proposed top-down approach, based on the progressive refinement of the NoC description, from its functional specification (Sect. 4) to its...

Network on Chip (NoC) has emerged as a promising interconnection paradigm for complex on-chip communications. As fabrication cost is high, model based design of NoC and early exploration to make proper design decisions are important challenges in NoCs. To tackle these challenges, we use formal methods and utilize their expressivity and flexibility to model different behaviors of a NoC and their...

We examined the role of nitric oxide (NO) in adrenal catecholamine secretion in response to splanchnic nerve stimulation (SNS) and exogenous acetylcholine (ACh) in anesthetized dogs. The NO synthase inhibitor N ω-nitro-l-arginine methyl ester (l-NAME), NO donor 3-(2-hydroxy-1-methyl-2-nitrosohydrazino)- N-methyl-1-propanamine (NOC 7), and ACh were administered intra-arterially into the adrenal ...

High red meat diets have been linked with risk of sporadic colorectal cancer; but their effects on mutations which occur in this cancer are unknown. G-->A transitions in K-ras occur in colorectal cancer and are characteristic of the effects of alkylating agents such as N-nitroso compounds (NOC). We studied th effect of red meat consumption on faecal NOC levels in eight male volunteers who consu...

Three dimensional integrated circuits (3D IC) is an emerging technology to overcome the interconnect delay and power limitations. A 3D IC consists of two or more independently manufactured ICs that are vertically stacked on top of each other this is referred to as a tier. An interconnection between the tiers is made by through-silicon vias (TSV). Three dimensional (3D) ICs are capable of achiev...

Networks-on-Chip (NoCs) are a new paradigm for the design of integrated systems. NoCs address design complexity and physical issues in ASIC and FPGA designs. In this paper, we present a scalable, mesochronous NoC architecture for an FPGA. A special hybrid switching scheme has been developed for globally asynchronous locally synchronous (GALS) operation of the whole NoC-based system. The NoC was...

Network-on-Chip (NoC) is a packet switched onchip communication network designed using a layered methodology i.e. “routes packets, not wires”. It is an efficient on chip communication architecture for System on Chip (SoC) architectures. NoCs solved the disadvantages of SoCs and are scalable. Each route in NoC includes some routers and it takes a few clock periods by passing a router. When the n...

Massive manycore embedded processors with network-on-chip (NoC) architectures are becoming common. These architectures provide higher processing capability due to an abundance of cores. They provide native core-to-core communication that can be exploited via message passing to provide system scalability. Despite these advantages, manycores pose predictability challenges that can affect both per...
