Referenssträngar
Referenssträngar, also known as reference strings, are sequences of page numbers or memory addresses that are used to simulate and analyze the performance of page replacement algorithms in virtual memory management. These strings are typically generated by tracing the memory access patterns of a running program or by simulating a hypothetical workload. The primary purpose of referenssträngar is to evaluate the efficiency of different page replacement strategies, such as First-In-First-Out (FIFO), Least Recently Used (LRU), and Optimal, in terms of page faults and overall system performance.
The construction of a referenssträng involves recording the sequence of memory accesses made by a program.
Analyzing a referenssträng requires applying various page replacement algorithms to the sequence of memory accesses. The
Referenssträngar are valuable tools for researchers and system designers as they provide a standardized way to
