The multiplication of the number of cores inside embedded systems has raised the pressure on the memory hierarchy. The cost of coherence protocol and the scalability problem of the memory hierarchy is now-a-days a major issue. In this paper, a specific data management for read-only data is investigated because these data can be duplicated in several memories without being tracked. Based on analysis of standard benchmarks for embedded systems, this analysis shows that read-only data represent 62% of all the data used by applications and 18% of all the memory accesses.
