  The systems supporting signal and image applications process large amount of
data. That involves an intensive use of the memory which becomes the bottleneck
of systems. Memory limits performances and represents a significant proportion
of total consumption. In the development high level synthesis tool called GAUT
Low Power, we are interested in the synthesis of the memory unit. In this work,
we integrate the data storage and data transfert to constraint the high level
synthesis of the datapath's execution unit.
