In computer science, trace-based simulation refers to system simulation performed by looking at traces of program execution or system component access with. Microarchitecture simulation is an important technique in computer architecture research and A trace-driven simulation reads a fixed sequence of trace records from a file as an input. These trace records usually represent memory references, . Definition of Trace-Driven Simulation: It is an important tool in many simulation applications in which the model's inputs are derived from a sequence of.

Trace driven simulation is a well known method for evaluating computer architecture options and is the technique of choice in most published cache and memo. The advantages and disadvantages of trace-driven modeling are examined and comparison to conventional distribution driven simulation techniques is made. In a trace-driven simulation whenever a value for a random variable is needed by the simulation, it is read from a data file. When it is practical.

This has lead to a growing interest in applying sampling techniques to reduce trace driven simulation costs. A trace-driven simulation [1] reads a fixed sequence of trace records from a file as an input. Namespaces Article Talk. Sign In. This paper reports on same experiments in trace sampling and discusses a prediction method for resolving cold-start or fill references when simulating with a sampled trace. However, the execution-driven simulation is much slower than the trace-driven simulation because it has to process each instruction one-by-one and update all statuses of the microarchitecture components involved.
