System-level Code Transformations
•The major principles of source-to-source transformations of the DTSE methodology are:
–Global data-flow transformation to avoid redundant transfers.
–Global loop and control flow transformations to increase locality of reference.
–Data reuse exploration to exploit the available memory hierarchy.          
–SDRAM memory organization.
–Data layout decisions to reduce the memory size and improve the cache hit rates.
