Abstract
Methods and apparatus for implementing a pixel page system providing swapped pixel pages for use with a GLV (grating light valve). In one implementation, a swapped pixel page system includes: a data source, providing pixel data for pixels in a first order, where each pixel is in a frame of pixels, the frame having horizontal rows of pixels, vertical columns of pixels, an upper half, and a lower half; a data destination, receiving pixel data for pixels in a second order; and at least two memory devices, each memory device having a plurality of memory pages including a plurality of memory locations, each memory location having an address; where pixel data for each pixel corresponds to an entry in one of a plurality of swapped pixel pages, each swapped pixel page having a plurality of pixel page rows each including a plurality of pixels and a plurality of pixel page columns each including a plurality of pixels, where pixel data is stored to the memory devices in the first order and retrieved from the memory devices in the second order, and where each memory page stores pixel data in multiple locations according to the first order and stores pixel data in multiple locations according t…
