Abstract

Recent experiments for the realisation of data-dominatedmulti-media applications have clearly demonstrated that the mainpower (and largely also area) cost is situated in the memory unitsand the (bus) communication hardware. On the custom hardware side,several system level memory management related methodologies arebeing proposed which promise very large savings on power and also onarea while still meeting the real-time constraints. Unfortunately,on the software side these methodologies are not applicable as such.In order to alleviate this situation for systems-on-a-chip with aheterogeneous mix of processors, novel methodology and architectureapproaches are required. In this research summary paper, thecurrently available solutions will be reviewed and some majorproblems to be solved in the future are identified.
