Thread Synchronization and Coordination
Comprehensive guide to condition variables for thread synchronization. Covers wait/signal mechanisms, producer-consumer problem, bounded buffers, proper locking with condition variables.
Virtual Memory Management
Solutions for reducing page table overhead. Covers larger pages, hybrid paging-segmentation approaches, and multi-level page table structures to minimize memory consumption while managing virtual memory.
Memory Management – Fragmentation, Free Lists and Allocation
Addresses free space management in memory allocation systems. Covers fragmentation, splitting, coalescing, memory headers, free lists, and allocation strategies like best-fit, worst-fit, and first-fit.
Virtual Memory and Disk Swapping
Extends virtual memory beyond physical RAM using disk swap space. Discusses present bit, page faults, page-fault handlers, swap space management, and mechanisms for handling memory larger than physical RAM.
Memory Virtualization Mechanisms
Covers hardware-based address translation using base and bounds registers for memory virtualization. Explains dynamic relocation, hardware requirements for memory protection, and OS involvement in virtual memory.
