Nowadays, network-on-chip (NoC) routers become important in several applications including mobile technology and digital communication. Multiple cores/processors are typically coupled using NoC routers, which considerably improve integrated circuit performance in terms of power, latency, throughput, and area. So, a novel 4 × 4 topology-based NoC router using multi-priority based iterative round-robin matching with slip (MPiSLIP) routing algorithm is implemented in this work. The proposed work contains different operational blocks classification such as route computation using static straight allocator, route controlling using MPiSLIP arbiter, a crossbar switch, combined parallel virtual channel and switch allocation unit, look ahead bypass route computation (LBRC), and input-output ports. The MPiSLIP routing mechanism also determines the priorities necessary for route development. Finally, by bypassing the switches and fulfilling all of the priories in a look-ahead manner, LBRC is employed to establish the effective path between input ports and output ports. The simulation results show that the proposed MPiSLIP-based NoC routing method resulted in a reduced area, power, and latency as compared to the open-source NoCs, multi-processor NoCs, multi-core NoCs, and conventional routing algorithms. 相似文献

In this work, a low power and variability-aware static random access memory (SRAM) architecture based on a twelve-transistor (12T) cell is proposed. This cell obtains low static power dissipation due to a parallel global latch (G-latch) and storage latch (S-latch), along with a global wordline (GWL), which offer a high cell ratio and pull-up ratio for reliable read and write operations and a low cell ratio and pull-up ratio during idle mode to reduce the standby power dissipation. In the idle state, only the S-latch stores bits, while the G-latch is isolated from the S-latch and the GWL is deactivated. The leakage power consumption of the proposed SRAM cell is thereby reduced by 38.7% compared to that of the conventional six-transistor (6T) SRAM cell. This paper evaluates the impact of the chip supply voltage and surrounding temperature variations on the standby leakage power and observes considerable improvement in the power dissipation. The read/write access delay, read static noise margin (SNM) and write SNM were evaluated, and the results were compared with those of the standard 6T SRAM cell. The proposed cell, when compared with the existing cell using the Monte Carlo method, shows an appreciable improvement in the standby power dissipation and layout area. 相似文献

To ensure the safety of nuclear power plants (NPPs), nuclear regulatory agencies set technical specifications (TSs). TSs define the safety‐related operational measures and specify essential requirements and set specific limitations that is necessarily be followed by a nuclear industry to meet the requirements for the safety of an NPP. One of the important bases for the setting of TSs is the estimates of the availability and reliability of various systems and costs associated with an NPP. In this work, authors have presented a framework based upon a hodiernal nature‐inspired metaheuristic called multiobjective gray wolf optimizer (MOGWO) algorithm, which mimic the hierarchal and hunting behavior of gray wolves (Canis lupus), for technical specifications optimization of residual heat removal system (RHRS) of an NPP safety system. The efficiency of MOGWO in optimizing the TSs is demonstrated by comparing its results with a very popular swarm‐based optimization technique named multiobjective particle swarm optimization (MOPSO). 相似文献

Sorghum starch is hydroxypropylated with propylene oxide for 20 h under alkaline conditions and its physicochemical and structural properties are compared with native and alkali modified starches using the same procedure but without propylene oxide. The study demonstrates that functional effects of the hydroxypropylation are not a sum total of alkali modification and addition of propylene oxide. Syneresis and pasting temperature decrease following both modifications. However, alkali modification, as compared to hydroxypropylation, shows a greater decrease in the pasting temperature. Apparent amylose content and swelling power increase after hydroxypropylation. The starch granular structure remains intact after both modifications. The data support that hydroxypropylated starch can be a texturing agent for bakery products such as cookies as documented from data of cutting force and smooth surface of cookies. 相似文献

In this study, a homogeneous blend of starch and dietary fiber (DF), which contained both water-soluble and water-insoluble compositions, is prepared in ionic liquids. The morphology and structure of the regenerated blend are studied using a scanning electron microscope (SEM), atomic force microscopy (AFM), differential scanning calorimetry (DSC), Fourier transform infrared (FTIR), X-ray diffraction (XRD), and thermogravimetric analysis (TGA). It is found that the morphological structures of both original starch and DF are destroyed, and a homogeneous morphological structure is formed for the blend during the dissolution-regeneration process in ionic liquids. Though no new chemical combination is observed from the infrared spectrum of the regenerated blend, the shift of absorption peaks appeared due to the destruction of the hydrogen bond during the dissolution of ionic liquids. The XRD results showed that the regenerated blend showed a disordered structure which is different from the orderly crystalline structure of original starch and DF. The disordered structure may result in the reduction of thermal stability. Among three ionic liquids 1-allyl-3-methylimidazole chloride ([AMIM]Cl), 1-ethyl-3-methylimidazole chloride ([EMIM]Cl), and 1-ethyl-3-methylimidazole acetate ([EMIM]OAc), [EMIM]Cl has the best solubility to the blend and also has the most disruptive to the native structure of starch and DF, correspondingly. 相似文献

There is an urgent need for new materials to treat bacterial infections. In order to improve antibacterial delivery, an anti‐infective nanomaterial is developed that utilizes two strategies for localization: i) a biodegradable nanoparticle carrier to localize therapeutics within the tissue, and ii) a novel tandem peptide cargo to localize payload to bacterial membranes. First, a library of antibacterial peptides is screened that combines a membrane‐localizing peptide with a toxic peptide cargo and discovers a tandem peptide that displays synergy between the two domains and is able to kill Pseudomonas aeruginosa at sub‐micromolar concentrations. To apply this material to the lung, the tandem peptide is loaded into porous silicon nanoparticles (pSiNPs). Charged peptide payloads are loaded into the pores of the pSiNP at ≈30% mass loading and ≈90% loading efficiency using phosphonate surface chemistry. When delivered to the lungs of mice, this anti‐infective nanomaterial exhibits improved safety profiles over free peptides. Moreover, treatment of a lung infection of P. aeruginosa results in a large reduction in bacterial numbers and markedly improves survival compared to untreated mice. Collectively, this study presents the selection of a bifunctional peptide‐based anti‐infective agent and its delivery via biodegradable nanoparticles for application to an animal model of lung infection. 相似文献

AbstractA numerical model was developed to analyze the hydrodynamics of TiO2-water nanofluids flowing through straight and coiled tubes in laminar flow regime. Pressure drop of nanofluid predicted from this model was validated with experiments for identical dimensions of tubes and process conditions. The velocity contours of flow in straight as well as coiled tube were examined. The present study revealed that there was 74% decrease in pressure drop when the straight tube diameter was increased from 0.003?m to 0.0072?m. There was 46–51% decrease in friction factor when curvature ratio (Dc/dt) was increased from 7.54 to 12.24 for 200<De?<?850. 相似文献
