With continuing progress in VLSI and ASIC technologies digital signal processing DSP algorithms have continued to find great use in increasingly wide application areas. DSP has gained popularity also in embedded systems although these systems set challenging constraints for implementations. Embedded systems contain limited resources thus embedded DSP systems must balance tradeoffs between the requirements on computational power and computational resources. Energy efficiency has been important in battery-powered devices but nowadays also the limited heat dissipation in small devices calls for low-power consumption. Successful implementation of DSP applications in embedded systems requires tailoring which in turn sets challenges for design methodologies. For this special issue we received 14 submissions and a collection of seven papers was finally accepted. The special issue is opened by Observations on power-efficiency trends in mobile communication devices where the authors O. Silven and K. Jyrkka analyze the power consumption in the current mobile communication devices. Several bottlenecks in the current implementation style have been identified thus the paper provides a good motivation for the following papers. In The Sandbridge SB3011
