Nowadays, the computational systems (multi and uniprocessors) need to avoid the cache
coherence problem. There are some techniques to solve this problem. The MESI cache
coherence protocol is one of them. This paper presents a simulator of the MESI protocol
which is used for teaching the cache memory coherence on the computer systems with
hierarchical memory system and for explaining the process of the cache memory location in
multilevel cache memory systems. The paper shows a description of the course in which the
simulator is used, a short explanation about the MESI protocol and how the simulator
works. Then, some experimental results in a real teaching environment are described.
