Re: Dope-Vectors for low energy compliers

There has been some reserach already on the data allocation problem at the
level of an array . I guess data /source transformations can be used to
achieve a finer granularity .


  A few papers you might want to look at


1.off-chip vs On chip memory : the data partitioning problem in embedded
processor based systems
by preeti ranjan panda et al university of california , irvie


2.memory energy mangement using software and hardware directed power control
