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

Introduction

The Universal Asynchronous Receiver Transmitter (UART) is the most widely used serial data communication circuit ever. UARTs allow full duplex communication over serial communication links as RS232. UARTs are available as inexpensive standard products from many semiconductor suppliers, making it unlikely that this specific design is useful by itself.

The basic functions of a UART are a microprocessor interface, double buffering of transmitter data, frame generation, parity generation, parallel to serial conversion, double buf ....etc

Abstract
A method is described for synthesizing asynchronouscircuits based on the Handshake Circuit paradigm but employinga data-driven, rather than a control-driven, style. This approachattempts to combine the performance advantages of data-drivenasynchronous design styles with the handshake circuit style of constructionused in existing syntax-directed synthesis. The methodis demonstrated on a significant design—a 32-bit microprocessor.This example shows that the data-driven circuit style providesbetter performance than control-drive ....etc

Computer chips of today are synchronous. They contain a main clock, which controls the timing of the entire chips. There are problems, however, involved with these clocked designs that are common today.One problem is speed. A chip can only work as fast as its slowest component. Therefore, if one part of the chip is especially slow, the other parts of the chip are forced to sit idle. This wasted computed time is obviously detrimental to the speed of the chip.

New problems with speeding up a clocked chip are just around the corn ....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

These computers include the entire spectrum of PCs, through professional workstations up to super-computers. As the performance of computers has increased, so too has the demand for communication between all systems for exchanging data, or between central servers and the associated host computer system.The replacement of copper with fiber and the advancement sin digital communication and encoding are at the heart of several developments that will change the communication infrastructure. The former development has provided us with hu ....etc
