. . . . . 278 x CONTENTS Chapter 1 Introduction 1.1 Synchronization In common use, "synchronization" means making two things happen at the same time. In computer systems, synchronization is a little more general; it refers to relationships among events—any number of events, and any kind of...
well... I usually use low-level synchronization techniques for speed and scalability, and not for lock-free (forward progress) properties (btw, is your emulated DWCAS lock-free or wait-free?). So 3 CASes looks like overkill, there is private rule - if lock-free algo issues ...
Even very experienced firmware developers too often fail to fully appreciate the importance of using the correct tool for the job at hand. And, unfortunately, misuse of these two distinct types of synchronization primitives can lead to difficult to debug defects in embedded software, with potentially...
Dijkstra around 1965 to allow synchronization and communication between co-operating sequential processes [Dij68a], initially on the THE operating system [Dij68b]. The first main application was to ensure that such processes could access a common resource under mutual exclusion. In recent times, ...

To avoid deadlocks in the semaphore, the Wait and Signal operations are required to be executed in the correct order. Using semaphores at a large scale is impractical; as their use leads to loss of modularity and this happens because the wait() and signal() operations prevent the creation of...
A semaphore manager data structure for managing semaphores in a multi-tasking computer system is disclosed. The data structure comprises of a multiple of indices corresponding to each class, a multipl
