To take advantage of minimum energy consumption in sub-threshold, systems are required to have robustness to variability. In sub-threshold, exponential drain current dependence on the threshold voltage produces large sensitivities to variations. Adaptive systems are required to respond to these conditions. One adaptive method, called timing error detection (TED), eliminates traditional safety margins...
A new simple method for shifting reference image data within an analog cellular array for variable block-size motion estimation is presented. The method leads to a greatly reduced number of neighborhood connections for each cell of the array, and allows for all shifts within the Marku, J., et al, (2007) search area to be performed in a single step, with simple digital controls. The new shift circuitry,...
