Operating System Assignment: Threads, Memory, Processes Solutions

This assignment solution addresses core operating system concepts, including threads, memory management, and process synchronization. The solution begins with an analysis of thread synchronization using semaphores in the context of a truck and wagon shunting problem. It then delves into memory allocation algorithms, comparing first-fit, best-fit, and worst-fit strategies, and analyzes page table structures, calculating memory access times with and without a Translation Lookaside Buffer (TLB). A monitor implementation for accessing an external sensor is provided, followed by a discussion of potential issues like race conditions and deadlocks, and a modified pseudo-code using semaphores to solve these problems. The assignment covers critical sections, and provides a solution using semaphores to synchronize access to shared resources, such as frames from a camera, using functions like GetFrame and ShowFrame. The solution also includes memory allocation for frames and the use of stacks and queues for frame management.
