This message transmission lag delays the entry of threads into the critical section, and the system efficiency decreases. Mutex Locks As the synchronization hardware solution is not easy to implement for everyone, a strict software approach called Mutex Locks was introduced. In this approach, in the...
5.15 Consider how to implement a mutex lock using an atomic hardware instruction. Assume that the following structure defining the mutex lock is available: 考虑如何使用原子硬件指令实现互斥锁。 假设以下定义互斥锁的结构可用: typedefstruct{intavailable;}lock; (available == 0)indicates that the lock i...
How Hardware Handles Synchronization Emulating Hardware A Sample Operating System Ruediger R. Asche Software ConsultantOctober 1997AbstractThis article describes ways to emulate the synchronization mechanisms found in operating systems (that is, interrupt-driven concurrency and appropriate mutual exclusion pri...

No matter what hardware platform you’re using Windows on, this is guaranteed to work. One-time initialization allows for both synchronous and asynchronous initialization. First we’ll take a look at synchronous initialization. Conceptually, synchronous initialization works the same way ...
lock and a sequence number. The spin lock is used to protect the list while entries are inserted or deleted. The sequence number is incremented each time an entry is inserted or deleted. On some hardware architectures, using a sequence number enables these routines to avoid using a spin lock...
