This paper describes a sub-mW motion estimation processor core for MPEG-4 video encoding. It features a Gradient Descent Search algorithm whose computation power is only 7% of the...
In 90-nm technology, dynamic power is still the largest power source in FPGAs [1], and signal glitches contribute a large portion of the dynamic power consumption. Previous powera...
Abstract—We consider the distributed estimation of an unknown vector signal in a resource constrained sensor network with a fusion center. Due to power and bandwidth limitations,...
