Abstract

Disclosed is a method to extract data from memories, at several locations, and more particularly to extract blocks in 2-dimensional arrays of values (e.g. images) stored as a sequence of numbers. It consists in preprocessing the mask used for the extraction that could represent any shape (e.g. a square of 8x8 pixels) and, combined with locations, provides blocks of data. Assuming that, th (Point i .x,Point i .y) are the relative coordinates of the i point of the mask, th (Location j .x,Location j.y) are the coordinates of the j
