Abstract: A vacuum tool configured to be removably coupled to hose or wand of a vacuum includes a body including a first end, a second end, and a first longitudinal axis extending between the first end and the second end. The vacuum tool also includes a head coupled to the first end of the body, a connection portion coupled to the second end of the body and configured to couple the body to a hose or wand of a vacuum cleaner, and a brush coupled to the head. The brush includes an elongate support defining a second axis perpendicular to the longitudinal axis of the body and configured to couple the brush to the head, and a plurality of bristles positioned on the elongate support.

Abstract: A system and method for binding instructions to a graphical processing unit (GPU) includes a GPU configured to receive bindlessly compiled instructions and interpret the bindlessly compiled instruction at runtime to identify a needed conversion The GPU generates a conversion information based on the bindlessly compiled instruction and needed conversion and converts the bindlessly compiled instruction according to the conversion information to generate a bound format instruction. The GPU may then execute the bound format instruction.

Abstract: The VPC unit and setup unit of a graphics processing subsystem perform culling operations. The VPC unit performs culling operations on geometric primitives falling within a specific criteria, such as having a property within of a numerical range limit. This limit reduces the complexity of the VPC unit. As increasing rendering complexity typically produces a large number of small primitives, the VPC unit culls many primitives despite its limitations. The VPC unit also includes a cache for storing previously processed vertices in their transformed form, along with previously computed culling information. This increases the VPC unit throughput by reducing the number of memory accesses and culling operations to be performed. The setup unit performs culling operations on any general primitive that cannot be culled by the VPC unit. By performing a first series of culling operations in the VPC unit, the processing burden on the setup unit is decreased.

Abstract: Systems and methods for delivering two data streams via two buses allow one of the buses to be used for delivering selected elements of the data stream that is primarily being delivered by the other bus. At an input rerouting circuit, the selected elements are rerouted from the second data stream into the first data stream; a token inserted in the second data stream identifies a position of the rerouted element. The modified streams are transmitted by the two buses. A receiving circuit reinserts the rerouted data element into the second data stream at the sequential position identified by the placeholder token.

Abstract: Graphics processing devices and methods are provided for culling small primitives that do not cover any pixels. A boundary (e.g., a diamond) is defined around a pixel center, with pixel coverage being determined for some types of primitives based on whether the boundary is crossed. The boundaries divide the raster into internal regions and external regions. Each region is assigned a unique canonical identifier. Each vertex of a primitive is assigned the canonical identifier corresponding to the region that contains that vertex. The canonical coordinates of the vertices are used to cull primitives that do not satisfy the boundary crossing coverage rules for any pixels.

Abstract: The VPC unit and setup unit of a graphics processing subsystem perform culling operations. The VPC unit performs culling operations on geometric primitives falling within a specific criteria, such as having a property within a numerical range limit of the VPC unit. This limitation reduces the complexity of the VPC unit. As increasing rendering complexity typically produces a large number of small primitives, the VPC unit can cull many primitives despite its culling limitations. The VPC unit also includes a cache for storing previously processed vertices in their transformed form, along with culling information previously computed for the vertices. To minimize memory bandwidth, the VPC unit retrieves vertex data used for culling operations first. After completing the culling operations, the VPC unit retrieves the attributes of a vertex only if the primitive has not been culled. The VPC unit applies a perspective correction factor to the vertex attributes.
