Abstract

Vol tage Scal ing (DVS), which adjusts the cl ock speed and suppl y vol tage dynamical l y, is an e#ective technique in reducing the energy consumption of embedded real -time systems. Unl1 e dynamic-priority real time schedul: g for which highl y e#ective DVS al]]'P hms are availACPb existing fixed-priority DVS al$O'Fb ms arelb] e#ective in energy e#ciency because they are based on ine#cient sl] k estimation methods. This paper describes an e#cient on-l] e sl: k estimation heuristic for the rate-monotonic (RM) schedul] g. The proposed heuristic estimates the sl ack times using the short term work-demand an al sis. The DVS al]P$] hm based on the proposed heuristic is al so presented. Experimental resul ts show that the proposed DVS al gorithm reduces the energy consumption by 25#42% over the existing rate-monotonic DVSalO1AP hms.
