Abstract:
A buffer page system, comprising:a data source, providing data elements in a first order; a data destination, receiving data elements in a second order; at least one memory device, each memory device having a plurality of memory pages including a plurality of memory locations, each memory location having an address; and where each data element corresponds to an entry in one of a plurality of buffer pages, each buffer page having a plurality of entries along a first dimension corresponding to the first order and a plurality of entries along a second dimension corresponding to the second order, and where data elements are stored to the memory device in the first order and retrieved from the memory device in the second order, and where each memory page stores data elements in multiple locations according to the first order and stores data elements in multiple locations according to the second order, where a data element is pixel data corresponding to a pixel in a frame of pixels, the frame having horizontal rows of pixels and vertical columns of pixels; and the buffer pages are pixel pages, each pixel page having a plurality of pixel page rows and a plurality of pixel page columns; where the data destination is a grating light valve system including one or more grating light valves, where each grating light valve sweeps one column at a time from left to right and from right to left in alternation, and where a counter is used to generate addresses, and further where the counter increments as each grating light valve sweeps from left to right and the counter decrements as each grating light valve sweeps from right to left.
