The generator creates all the necessary memory and control functionality for a functional spatio-temporal video processing system. The required memory architecture is automatically optimized and mapped to the FPGAs memory resources thus producing an efficient implementation in terms of used internal resources. The results in this paper show that the tool is able to efficiently and automatically generate all required memory management modules for both spatial and temporal real-time video processing systems.

INTRODUCTION In today s society it is apparent that video systems are generally becoming standard applications. These systems are playing a central role in the daily life of the majority of homes. Embedded video applications contained in home entertainment systems are becoming more and more complex as is the processing required. Real-time streamed video is common and this places significant constraints on the processing applications as the data rates increase towards high-definition television HDTV . Surveillance .
