There are many benefits to migrating from ARM architecture to Intel Atom micro-architecture, though there are challenges to overcome before the migration is complete. There are a number of decisions which need to be made related to the number of cores to use, whether to use a symmetric or asymmetric operating system, and most importantly will the real time requirements be met after the migration. This white paper lists decisions that need to be made in relation to latencies, cores and the order in which the decisions need to be implemented. This paper also covers the experiments which need to be conducted to gather data related to these decisions. A flow chart is provided to help make a more intelligent and informed decision on the migration.
