摘要： An optical signal generator is configured with an associated control system and driver configured to reduce speckle. Speckle reduction occurs by pulsing the drive signal between a first current level and a second current level. These pulses force the optical signal generator to introduce oscillations into the optical signal. The coherence of the emitted light is reduced during the period of oscillations in the optical signal, which reduces speckle. In one embodiment, the pulsing of the drive signal brings the drive signal down to a level near or below threshold, which in turn intermittently turns off the optical signal output. Returning the optical signal to a desired optical output intensity introduces the speckle reducing oscillation. The pulse frequency, and duty cycle is controlled by a duty cycle control signal to modulate overall optical power and adjust amount of despeckle.

摘要： A system is disclosed to automatically establish proper biasing for light sources in a color mixed projection system having multiple light sources which are active at the same time. Responsive to a feedback signal, a single DC-DC converter generates the bias voltage for the light sources. Comparators compare a headroom signal for each light source to a reference value to generate comparator output signals. The comparator output signals are processed by a channel selector and a digital filter/DAC module. The channel selector controls a switch to selectively provide and combine a headroom signal with an output of the digital filter/DAC module to create the feedback signal. By monitoring each headroom value, the bias voltage is adjusted, based on the feedback signal, until every headroom signal reaches the reference value thereby achieving sufficient biasing for every active light source in the color mixed projection system.

摘要： There is provided a multi-core system that provides automated task list generation, parallelism templates, and memory management. By constructing, profiling, and analyzing a sequential list of functions to be executed in a parallel fashion, corresponding parallel execution templates may be stored for future lookup in a database. A processor may then select a subset of functions from the sequential list of functions based on input data, select a template from the template database based on particular matching criteria such as high-level task parameters, finalize the template by resolving pointers and adding or removing transaction control blocks, and forward the resulting optimized task list to a scheduler for distribution to multiple slave processing cores. The processor may also analyze data dependencies between tasks to consolidate tasks working on the same data to a single core, thereby implementing memory management and efficient memory locality.
