Multimedia algorithms deal with enormous amounts of data transfers and storage,resulting in huge bandwidth requirements at the off-chip memory and system bus level.As a result the related energy consumption becomes critical. Even for execution time thebottleneck can shift from the CPU to the external bus load. This paper demonstratesa systematic software approach to reduce this system bus load. It consists of source-to-sourcecode transformations, that have to be applied before the conventional ILPcompilation. To illustrate this we use a cavity detection algorithm for medical imaging,that is mapped on an Intel Pentium® II processor
