In this survey, we review several approaches for predicting performance of NoC-based multicore systems, starting from the traffic models to the complex NoC models for latency evaluation. We first review typical traffic models to represent the application workloads in NoC. Specifically, we review Markovian and nonMarkovian (e.g., self-similar or long range memory dependent) traffic models and di...

© 2009 Chia-Ming Wu et al. 111 Network-on-chip (NoC) architecture provides a highperformance communication infrastructure for systemon-chip designs. Circuit-switched networks guarantee transmission latency and throughput; hence, they are suitable for NoC architecture with real-time traffic. In this paper, we propose an efficient integrated scheme which automatically maps application tasks onto ...

Study of Network-on-Chip (NoC) systems requires simulators capable of handling their unique characteristics. Toward this objective, a set of simulation models are developed based on NoC first principles and the DEVS framework. The components necessary to build simulation models for NoC are developed using Parallel DEVS and implemented in NoC-DEVS which extends the generalpurpose DEVS-Suite simu...

This work presents formal modeling of Network-on-Chip (NoC) considering detailed functional units NoC. The intricate NoC router components like buffer, switch, and arbiter is accomplished using Finite State Machine (FSM). As in the case a real NoC, parallel execution these carried out by maintaining synchronization between within each adjacent routers presented model. Important properties for c...

BACKGROUND AND PURPOSE Although activation of the N-methyl-D-aspartate (NMDA) receptor is thought to contribute to altered cerebrovascular regulation after traumatic brain injury, the effects of such injury on the vascular response to NMDA itself has been less well appreciated. The newly described opioid nociceptin/orphanin FQ (NOC/oFQ) elicits pial artery dilation, at least in part, in a prost...

This study characterized the effects of fluid percussion brain injury (FPI) on N-methyl-D-aspartate (NMDA)-induced vasodilation and determined the role of nociceptin/orphanin FQ (NOC/oFQ) in such changes as a function of age and time postinsult. FPI elevated cerebrospinal fluid (CSF) NOC/oFQ from 70 +/- 3 to 444 +/- 56 pg/ml ( approximately 10(-10) M) within 1 h and to 1,931 +/- 112 pg/ml withi...

This study determined whether nociceptin/orphanin FQ (NOC/oFQ) generates superoxide anion (O(2)(-)) in a protein kinase C (PKC)-dependent manner and whether such production contributes to hypoxic-ischemic (H-I) impairment of N-methyl-D-aspartate (NMDA)-induced pial artery dilation in newborn pigs equipped with closed cranial windows. Superoxide dismutase (SOD)-inhibitable nitroblue tetrazolium ...

Network on-chip (NoC) is a novel structural design template, which can be defied for complicated system level on-chip design. NoC has a potential to limit and present the bus-based communication. In this paper, the crisis to discuss is Low power consumption in an Asynchronous Network on-chip (NoC) level communication. NoC is implemented using FPGA which has less fabrication cost and reduces the...

The packet switching based Network-on-Chip (NoC) is an obvious interconnect design alternative to the shared bus, crossbar or ring based on-chip communication architecture used in System-on-Chips (SoCs). The advent of the three dimensional NoC (3D NoC) architecture attracts added interest as it offers improved performance and shorter global interconnect. In the 3D NoC architecture, topology pla...

A scaffold of axons consisting of a pair of longitudinal tracts and several commissures is established during early development of the vertebrate brain. We report here that NOC-2, a cell surface carbohydrate, is selectively expressed by a subpopulation of growing axons in this scaffold in Xenopus. NOC-2 is present on two glycoproteins, one of which is a novel glycoform of the neural cell adhesi...
