Abstract:

A cavity free, broadband approach for engineering photon emitter interactions via sub-wavelength confinement of optical fields near metallic nanostructures. When a single CdSe quantum dot (QD) is optically excited in close proximity to a silver nanowire (NW), emission from the QD couples directly to guided surface plasmons in the NW, causing the wire's ends to light up. Nonclassical photon correlations between the emission from the QD and the ends of the NW demonstrate that the latter stems from the generation of single, quantized plasmons. Results from a large number of devices show that the efficient coupling is accompanied by more than 2.5-fold enhancement of the QD spontaneous emission, in a good agreement with theoretical predictions.

Abstract:

The present disclosure relates to methods and devices for graphics processing including an apparatus, e.g., a GPU. The apparatus may receive a plurality of workloads based on a workload order, each of the plurality of workloads being received in the workload order including at least a first workload and a second workload. The apparatus may also allocate one or more workloads of the plurality of workloads to one or more wave slots. Additionally, the apparatus may execute the one or more allocated workloads at the one or more wave slots, such that at least the first workload is executed at the first wave slot and the second workload is executed at the second wave slot. The apparatus may also allocate at least one other workload of the plurality of workloads to at least one previously-allocated wave slot of the one or more wave slots.

International Classification:

G06T 1/60

Abstract:

The present disclosure relates to methods and apparatus for graphics processing. For example, disclosed techniques facilitate improving bindless state processing at a graphics processor. Aspects of the present disclosure can receive, at a graphics processor, a shader program including a preamble section and a main instructions section. Aspects of the present disclosure can also execute, with a scalar processor dedicated to processing preamble sections, instructions of the preamble section to implement a bindless mechanism for loading constant data associated with the shader program. Additionally, aspects of the present disclosure can distribute the main instructions section and the constant data to a streaming processor for executing the shader program.

International Classification:

G06T 1/20
G06T 1/60

Abstract:

The present disclosure relates to methods and apparatus for graphics processing. In some aspects, the apparatus can determine one or more context states of at least one context register in each of multiple wave slots. The apparatus can also send information corresponding to the one or more context states in one of the multiple wave slots to a context queue. Further, the apparatus can convert the information corresponding to the one or more context states to context information compatible with the context queue. The apparatus can also store the context information compatible with the context queue in the context queue. In some aspects, the apparatus can send the context information compatible with the context queue to one of the multiple wave slots. Additionally, the apparatus can convert the context information compatible with the context queue to the information corresponding to the one or more context states.
