In this paper we present a data prefetch policy for the execution of 3D interactive applications on coarse-grain reconfigurable architectures. User's actions not occurring at expected times combined with the volume of data involved in this kind of applications impact strongly in performance. We define a data prefetch scheme to avoid reconfigurable processing unit stalls due to operands unavailability through profiling methodologies and special search algorithms. Experimental results satisfy time constraints of interactive applications and show a power effective solution for them.
