It is clear that adaptivity at all levels, from functions to services, is a highly desired attribute in SDRs/CRs. Although you will primarily be exposed to adaptivity at the service and application level, adaptivity at the component and function level is necessary for implementation.

As CRs and multi-INT platforms become more prevalent, the need to dynamically adapt to changing conditions will increase and will ultimately become a competitive advantage for those vendors who are better able to accommodate different levels of adaptivity. PR FPGAs are ideally suited for driving adaptivity at all levels. PR FPGAs have sufficient granularity to allow you to reconfigure portions of the device down to the size of typical functions in an SDR/CR. They are also able to support whole applications.
