    Abstract: A method comprising: dividing a 3D space into a voxel grid comprising a plurality of voxels; associating a plurality of distance values with the plurality of voxels, each distance value based on a distance to a boundary of an object; selecting an approximate interpolation mode for stepping a ray through a first one or more voxels of the 3D space responsive to the first one or more voxels having distance values greater than a threshold; and detecting the ray reaching a second one or more voxels having distance values less than the first threshold; and responsively selecting a precise interpolation mode for stepping the ray through the second one or more voxels.

    Abstract: An apparatus includes a plurality of delay generators, a first plurality of flip-flop circuits, a second plurality of flip-flop circuits, and a third plurality of flip-flop circuits. The plurality of delay generators includes a data delay generator, an enable delay generator, and a reference delay generator. The first plurality of flip-flop circuits is coupled to the data delay generator to receive a delayed data input signal, and provide the delayed data input signal to a plurality of data input terminals of a memory circuit. The second plurality of flip-flop circuits is coupled to the enable delay generator to receive a delayed enable signal and provide the delayed enable signal to a plurality of enable terminals of the memory circuit. The third plurality of flip-flop circuits is coupled to an output terminal of the memory circuit. The reference delay generator provides a synchronized clock signal to the flip-flop circuits.

    Abstract: Some embodiments include apparatus and methods using an input stage and an output stage of a circuit. The input stage operates to receive an input signal and a clock signal and to provide an internal signal at an internal node based at least in part on the input signal. The input signal has levels in a first voltage range. The internal signal has levels in a second voltage range greater than the first voltage range. The output stage operates to receive the internal signal, the clock signal, and an additional signal generated based on the input signal. The output stage provides an output signal based at least in part on the input signal and the additional signal. The output signal has a third voltage range greater than the first voltage range.
