Abstract
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.
Claims18
A device comprising:
- a spatial light modulator comprising a plurality of masking-processors,
- wherein the plurality of masking processors comprise parallel processing elements (PPE) for computing a respective drive waveform for each pixel of a plurality of pixels on the spatial light modulator,
- wherein each masking-processor comprises logic circuitry for logically and/or arithmetically comparing one or more multiple-bit pixel control values to one or more multiple-bit match values,
- wherein the PPE are part of execution RAM (ERAM) and PPE processing (EPE) modules located on at least three sides of a mirror RAM (MRRAM) array of the spatial light modulator, and
- wherein each EPE module comprises ERAM for the PPE of the EPE module.
2 more elements
A device comprising:
- a spatial light modulator comprising parallel processing elements (PPE) for computing a respective drive waveform for each respective pixel of a plurality of pixels on the spatial light modulator, and
- a command sequencer for generating a sequence of one or more programmable match values,
- wherein each parallel processing element of the parallel processing elements comprises logic circuitry for logically and/or arithmetically comparing one or more multiple-bit pixel control values for a respective pixel of the plurality of pixels to the one or more programmable match values for the respective pixel, and
- wherein the PPE are part of execution RAM (ERAM) and PPE processing (EPE) modules located on at least three sides of a mirror RAM (MRRAM) array of the spatial light modulator, and
- wherein each EPE module comprises ERAM for the PPE of the EPE module.
2 more elements
A device comprising:
- a spatial light modulator comprising:
- parallel processing elements (PPE),
- a pixel control value storage, and
- a mirror RAM (MRRAM) array,
- wherein the PPE are part of execution RAM (ERAM) and PPE processing (EPE) modules located on at least three sides of the MRRAM array of the spatial light modulator, and
- wherein each EPE module comprises ERAM for the PPE of the EPE module.
3 more elements
A method comprising the following steps:
- (a) controlling a pixel of a spatial light modulator based on a first multiple-bit pixel control value,
- (b) ignoring one or more first bits of the first multiple-bit pixel control value to thereby form one or more ignored bits, and
- (c) storing one or more second bits for a second multiple-bit pixel control value in respective storage locations of the one or more ignored bits,
- wherein the pixel of the spatial light modulator is controlled based on the second multiple-bit pixel control value,
- wherein steps (a) and (b) are conducted by parallel processing elements (PPE) of the spatial light modulator, and
- wherein the PPE are part of execution RAM (ERAM) and PPE processing (EPE) modules located on at least three sides of an mirror RAM (MRRAM) array of the spatial light modulator, and
- wherein each EPE module comprises ERAM for the PPE of the EPE module.
