通過研究Linux的線程機制和信號量實現(xiàn)讀者寫者(Reader-Writer)問題并發(fā)控制。 1)寫-寫互斥：不能有兩個寫者同時進行寫操作； 2）讀-寫互斥：不能同時有一個線程在讀，而另一個線程在寫； 3）讀-讀允許：可以有一個或多個讀者在讀； 4）讀者優(yōu)先的附加限制：如果讀者申請進行讀操作時已有另一個讀者正在進行讀操作，則該讀者可直接開始讀操作； 5）寫者優(yōu)先的附加限制：如果一個讀者申請進行讀操作時已有另一個寫者在等待訪問共享資源，則該讀者必須等到?jīng)]有寫者處于等待狀態(tài)后才能開始讀操作。

pic mcu code:This application note describes the design and implementation of a USB Mass Storage Device (MSD) using a Secure Digital card, which should prove useful to developers of USB mass storage solutions. This application may be used as a stand-alone MSD or as a Secure Digital/Multimedia Card (SD/MMC) reader/ writer interface.

高速數(shù)字系統(tǒng)設計下載pdf:High-Speed Digital SystemDesign—A Handbook ofInterconnect Theory and DesignPracticesStephen H. HallGarrett W. HallJames A. McCallA Wiley-Interscience Publication JOHN WILEY & SONS, INC.New York • Chichester • Weinheim • Brisbane • Singapore • TorontoCopyright © 2000 by John Wiley & Sons, Inc.speeddigital systems at the platform level. The book walks the reader through everyrequired concept, from basic transmission line theory to digital timing analysis, high-speedmeasurement techniques, as well as many other topics. In doing so, a unique balancebetween theory and practical applications is achieved that will allow the reader not only tounderstand the nature of the problem, but also provide practical guidance to the solution.The level of theoretical understanding is such that the reader will be equipped to see beyondthe immediate practical application and solve problems not contained within these pages.Much of the information in this book has not been needed in past digital designs but isabsolutely necessary today. Most of the information covered here is not covered in standardcollege curricula, at least not in its focus on digital design, which is arguably one of the mostsignificant industries in electrical engineering.The focus of this book is on the design of robust high-volume, high-speed digital productssuch as computer systems, with particular attention paid to computer busses. However, thetheory presented is applicable to any high-speed digital system. All of the techniquescovered in this book have been applied in industry to actual digital products that have beensuccessfully produced and sold in high volume.Practicing engineers and graduate and undergraduate students who have completed basicelectromagnetic or microwave design classes are equipped to fully comprehend the theorypresented in this book. At a practical level, however, basic circuit theory is all thebackground required to apply the formulas in this book.

Generating next numbers in SQLServer should not be a problem. But problems arise when a customer asks for different types of next numbers that you cannot generate directly from SQL Server. This brief article describes how you would tackle this problem in different scenarios.
