INTROUCTION



The idea of using optical techniques to address the chip-to-chip interconnection problems has been around for a long time. However, it is only in the last few years that technology with a realistic promise of eventual commercial applications has emerged. Progress can be attributed to a shift away from trying to develop custom VSLI techniques with in-built optoelectronic capability, towards developing techniques to allow parallel arrays of separately fabricated optoelectronic devices to be tightly integrated with standard foun ....etc

Abstract:

In this paper, analysis of CDMA network with Optical Amplifiers has been done. As the optical amplifier provides gain as well as has nonlinear characterstics, gain is expected due to signal amplification as well as operation of SOAs as limiter due to gain saturation. In this paper results have been computed for with different SOA placements in a typical star topology employing CDMA. The results show that in a star topology network employing CDMA, placement of SOAs before CDMA decoder does provide benefit due to g ....etc

Free space optical communications is a line-of-sight (LOS) technology that transmits a modulated beam of visible or infrared light through the atmosphere for broadband communications. In a manner similar to fiber optical communications, free space optics uses a light emitting diode (LED) or laser (light amplification by stimulated emission of radiation) point source for data transmission. However, in free space optics, an energy beam is collimated and transmitted t ....etc

A SONOS memory cell is formed from a standard polysilicon NMOS transistor with the addition of a small sliver of silicon nitride inserted inside the transistor's gate oxide. The sliver of nitride is non-conductive but contains a large number of charge trapping sites able to hold an electrostatic charge. The nitride layer is electrically isolated from the surrounding transistor, although charges stored on the nitride directly affect the conductivity of the underlying transistor channel. The oxide/nitride sandwich typically consists of a 2 nm thi ....etc

A HIGH SPEED DISTRIBUTED FIFO SCHEME FOR MANAGING INTERCONNECTS

Abstract:- Interconnect delays are increasingly becoming the dominant source of performance degradation in the nano-meter regime, largely because the wires do not scale as well as the transistors. Scaling trends allow for complete systems to be built on a single chip (SoC), but they require long interconnects for global signals and clock distribution networks. The parasitic of these global interconnects make efficient and high-performance operation difficult. On-chip communicati ....etc

INTRODUCTION
Explosive information demand in the internet world is creating enormous needs for capacity expansion in next generation telecommunication networks. It is expected that the data- oriented network traffic will double every year. Optical networks are widely regarded as the ultimate solution to the bandwidth needs of future communication systems. Optical fiber links deployed between nodes are capable to carry terabits of information but the electronic switching at the nodes limit th ....etc

Abstract
Most device drivers have one ulterior motive and one target to achieve - deliver the maximum using the minimum. No matter how stable or feature rich a device driver might be, if it cannot perform in terms of high throughput and low CPU utilization, it is as good as any other run of the mill driver.The objective of this topic is to use the thinking out of the box concept and expose techniques, which go beyond just good programming principles to get that extra edge which can put your next driver into the elite group of high perform ....etc
