With the increasing complexity of software applications and the growth of data volume, the efficiency of the memorial system has become an important factor in increasing the processor's performance. Cash memory data plays an essential role in reducing access to the delay, and understanding the behavior of the "access area" is one of the most impressive factors that affect the Cache performance. The purpose of this project is to use SMPCCHE 2.0 simulator to analyze cash behavior when performing multiple programs through tracking and analysis of memory track files.
