Described are devices and methods for reducing the need for storage on a display panel, for reducing the required bandwidth to a display panel, for increasing the light-on time for a display panel.

Spatial light modulator with storage reducer

Described is a device comprising: an array of light modulating elements; and one or more processing elements for controlling each of the light modulating elements, wherein the light modulating elements are arranged in a two-dimensional array, and wherein the one or more processing elements are adapted to skip some bit locations and use other bit locations of bit values when performing multiple bit logical and/or arithmetic operations.

Allocating registers on a spatial light modulator

Described is a device comprising a spatial light modulator comprising a plurality of comparators for computing a respective drive for each pixel of a plurality of pixels.

Spatial light modulator with masking-comparators

Described is a device comprising a backplane including registers for holding instructions for controlling pulse widths that control light modulating elements of a spatial light modulator of a visual display device. The registers are connected to a plurality of processing elements for driving mirror/electrodes on the spatial light modulator using the instructions held in the registers.

Allocation registers on a spatial light modulator

A data processing apparatus including a multiplier unit forming a product from L bits of each two data buses of N bits each N is greater than L. The multiplier forms a N bit output having a first portion which is the L most significant bits of the of product and a second portion which is M other bits not including the L least significant bits of the product, where N is the sum of M and L. In the preferred embodiment the M other bits are derived from other bits of the two input data busses, such as the M other bits of the first input data bus. An arithmetic logic unit performs parallel operations (addition, subtraction, Boolean functions) controlled by the same instructions. This arithmetic logic unit is divisible into a selected number of sections for performing identical operations on independent sections of its inputs. The multiplier unit may form dual products from separate parts of the input data. A single instruction controlling both the multiplier unit and the arithmetic logic unit permits addition of dual products. The dual products are temporarily stored in a data register permitting the multiply and add operations to be pipelined. The dual products are formed in one data word and added by a rotate/mask and add operation in a three input arithmetic unit.

Long instruction word controlling plural independent processor operations

The present invention provides a various methods, systems and devices for controlling light modulating elements and/or spatial light modulators. In some embodiments of the present invention, a recursive feedback method is used to control light modulating elements and/or spatial light modulators.

Allocating memory on a spatial light modulator

The present invention provides a device comprising: a backplane controller including means for sequencing a series of instructions, wherein the instructions control memory accesses to data that is used to control one or more pulse widths that drive one or more mirrors/electrodes on a spatial light modulator that control one or more outputs of the spatial light modulator.

Mapping pixel values

Instructions controlling light modulating elements

Bit serial control of light modulating elements

Variable storage of bits on a backplane

Masked write on an array of drive bits

In one embodiment, the present invention, one or more light modulating elements are controlled by a method comprising the following steps: controlling at least one pulse width using recursive feedback; and driving an electrode means using the pulse width to thereby control a light modulating element of an array of light modulating elements. In other embodiments, the present invention provides a method and system for determining a pulse wave form for each line of a two-dimensional array of drive bits using a recursive feedback process, wherein each drive bit in the array of drive bits is in an initialized state; and for turning all of the drive bits to an off state to thereby produce a blanking interval between fields for an image, wherein control of each of the pulse wave forms is staggered in time.

Recursive feedback control of light modulating elements

Digital backplane

A method for processing data using a multiplexing architecture includes performing a selected one of a plurality of first multiplexer operations on the data and then a selected one of a plurality of second multiplexer operations. The first multiplexer operations include a pass operation and a plurality of bit rearrangement operations. The second multiplexer operations include a pass operation and a plurality of bit duplication operations which duplicates a selected bit or bits to a corresponding block of contiguous bits in the output. A result is then generated that reflects the outputs produced by first and second multiplexers respectively.
