Abstract
A formatter (13) for formatting data for use by a spatial light modulator (15) in an image display system (10). The formatter (13) converts data from pixel format to bit-plane format. The formatter (13) has a square array of memory cells (41), which are connected so that they can shift data either across the array from column to column (vertically) or down the array from row to row (horizontally). The loading of data to the array is toggled between vertical and horizontal loading (FIGS. 6A-6D). While the array is loaded vertically from one side, data is shifted out of the array at the other side. While the array is loaded horizontally from the top, data is shifted out at the bottom. Because of the orthogonal input versus output, the output data is arranged by bit-weight rather than by pixel.
