Diversity of the Embedded Systems The range of embedded systems is extremely diverse both in terms of its scale and nature. There is currently no effective way of classifying the various systems.  Embedded device total cost * It is also necessary to add in a time-to-market factor. ！ Today development costs have become a significant factor in mass-production.
