A method includes transferring, by a memory controller from non-volatile memory to volatile memory, a bit sequence comprising video data and control information and transferring, by a first programmable real-time unit (PRU) from the volatile memory to a scratchpad register, the bit sequence. The method also includes transferring, by a second PRU from the scratchpad register to a general purpose input output (GPIO) register, the bit sequence, where the GPIO register is adapted to be coupled to a spatial light modulator (SLM).

Method, device, and system for spatial light modulator control

An example headlight includes: a multi-segment illumination source comprising: a first illumination source segment; and a second illumination source segment; driver circuitry coupled to the multi-segment illumination source, the driver circuitry comprising: a first driver coupled to the first illumination source segment, the first driver configured to generate a first drive signal to cause the first illumination source segment to produce a first light having a first brightness; and a second driver coupled to the second illumination source segment, the second driver configured to generate a second drive signal to cause the second illumination source segment to produce a second light having a second brightness; and a spatial light modulator (SLM) optically coupled to the multi-segment illumination source, the SLM configured to: receive the first light; modulate the first light to produce first modulated light; receive the second light; and modulate the second light to produce second modulated light.
