Abstract
Methods and apparatus for implementing a pixel page system providing pixel pages optimized for use with a GLV (grating light valve). In one implementation, a system includes: a data source, providing pixel data for pixels in a first order, each pixel in a frame having rows and columns of pixels; a data destination, receiving pixel data for pixels in a second order; at least one memory device including memory pages having memory locations; pixel data for each pixel corresponds to an entry in a pixel page, each pixel page having rows and columns and including pixels, the pixel pages optimized for use with a GLV. Pixel data is stored to memory in the first order and retrieved in the second order. And each memory page stores pixel data in multiple locations according to the first order and stores pixel data in multiple locations according to the second order.
