Abstract

A spatial light modulator having a double-buffering pixel value storage mechanism. A double-buffering mechanism enabling sparse refresh. A double-buffering value storage mechanism suitable for use with a serial or raster value producer and a value consumer, especially those in which it is desirable to consume an entire, completed frame or set of values at a time, and particularly those in which it is desirable to enable the producer to continue producing serially while the consumer is consuming in parallel fashion.
