DESIGN AND IMPLEMENTATION OF ASYNCHRONOUS FIFO FOR EMBEDDED APPLICATIONS

A FIFO is used as a First In-First Out memory buffer between two asynchronous systems with simultaneous write and read access to and from the FIFO, these accesses being independent of one another. Data written into a FIFO is sequentially read out in a pipelined manner, such that the first data written into a FIFO will be the first data read out of the FIFO.

FIFO status flag outputs are a function of the comparison of the respective write and read pointers. A FIFO w ....etc

VLSI based asynchronous Receiver and Transmitter

The aim of this project is to design and implement an asynchronous receiver,
transmitter using verilog hardware description language. In this project we have
used serial mode of transmission because in parallel mode of transmission we need
‘n’ number of cable to transmit “n” bits of data. The following features mainly
distinguishes our project from other similar devices
- full duplex operation
- standard data format
- even ....etc

Optical Networking and Dense Wavelength Division Multiplexing


This paper deals with the twin concepts of optical networking and dense wavelength division multiplexing. The paper talks about the various optical network architectures and the various components of an all-optical network like Optical Amplifiers, Optical Add/Drop Multiplexers, Optical Splitters etc. Important optical networking concepts like wavelength routing and wavelength conversion are explained in detail. Finally this paper deals ....etc

MAC protocols have been studied under different contexts for decades. In decentralized MAC protocols, transmitter-receiver pairs make independent decisions, which are often sub-optimal due to insufficient knowledge about the communication environment. In this paper, we introduce control-plane cooperation at the MAC layer, where neighboring nodes share control information with transmitter-receiver pairs to aid them in making more informed decisions. This augments conventional cooperation, which sits at the data plane where intermediate nodes hel ....etc

Abstract
Medium access control (MAC) protocols have been studied under different contexts for decades. In decentralized contexts, transmitter-receiver pairs make independent decisions, which are often suboptimal due to insufficient knowledge about the communication environment. In this paper, we introduce ....etc

Overview
Multiplexing is sending multiple signals or streams of data on an information line at the same time in the form of a single, more complex signal and then separating the signals at the receiving end.
Inverse Multiplexing is combining multiple low speed streams of data to form a single higher-speed data stream. The sending and receiving ends use an inverse multiplexer with one high speed input stream.
Analog Transmission
Each signal is assig ....etc

Synchronous& Asynchronous Multiplexing
• Depending on the need of synchronization between transmitter and receiver, the multiplexing system are classified as
• Synchronous multiplexing.
• Asynchronous multiplexing.
Synchronous multiplexing
• In the synchronous multiplexer, a synchronizing signal is required to be sent alongwith the data.
• For proper operation of synchronous multiplexer, synchronization between the transmitter and receiver is essential.
• In synchronous multiplexing a sin ....etc
