Method and Device for Maximizing Memory System Bandwidth by Accessing Data in a Dynamically Determined Order
Microprocessor performance has increased by 50−100 percent per year in the last decade, while DRAM performance has risen only 10−15 percent per year. Memory bandwidth, therefore, is rapidly becoming the performance bottleneck in the application of high-performance microprocessors to vector-like algorithms.This invention is a method of rapid...

A Novel Spline-Based Algorithm for Multidimensional Displacement and Strain Estimation
Researchers at the University of Virginia have developed a novel motion estimation algorithm based on a continuous representation of discrete-sample images, with accuracy better than one 100th of a sample. A novel strategy is employed to reduce computational cost and minimize memory requirements. In addition to rigid body motion, local stretching/compression...
