Simulation

Definition

Simulation refers to the process of creating a virtual model of a system or a process in order to analyze and understand its behavior under various conditions. In the context of cache compression techniques, simulation is used to evaluate how different compression algorithms can impact cache performance, helping designers optimize memory usage and access speeds. This approach allows for testing hypotheses and configurations without the need for physical hardware, making it a cost-effective way to explore improvements.
