摘要： A deblocking filter module can be used in a video processing device that processes a video input signal in accordance with a plurality of coding parameters. The deblocking filter module includes an adaptive deblocking filter that receives a plurality of samples and produces a plurality of filtered samples in response thereto, the adaptive deblocking filter having at least one filter parameter that is controllable in response to a filter control signal. A filter control module generates the filter control signal based on the plurality of coding parameters.

摘要： A shader unit is configured to provide an increased and dynamically changeable amount of ALU processing bandwidth. The shader unit includes a plurality of ALUs for processing pixel data according to a shader program. Each of the ALUs is configurable to be enabled and disabled. When disabled, the ALU is powered off, thereby reducing the power consumption of the shader unit. In one embodiment, the plurality of ALUs are logically configured into groups called ALU-pipes, each of which can be enabled and disabled. When an ALU-pipe is disabled, each ALU associated with the disabled ALU-pipe is disabled. The shader unit includes a sequencer that executes the shader program, determines the number of ALUs to be enabled, receives an input data stream of pixel data, assigns groups of pixel data to each enabled ALU, sends the assigned pixel data to their respective ALUs, and sends ALU instructions to the ALUs to process the received pixel data according to the shader program.

摘要： Embodiments described herein provide a programmable mapping scheme for mapping information to resources of a system. In an embodiment, a programmable lattice method operates to map information to resources of a system. For example, the programmable lattice method can be used to map pixel data to graphics processing resources of a graphics processing system. In another embodiment, a programmable hybrid method operates to map information to resources of a system. For example, the programmable hybrid method can be used to map pixel data to graphics processing resources of a graphics processing system. The mapping methods described are applicable to any multi-dimensional array processing (e.g., 2D and 3D). The methods provide a uniform distribution of resources and tend to reduce resource collisions when allocating information to a resource.

摘要： Embodiments of a system and method for handling interrupts are described herein. In an embodiment interrupts from various client components in a system (also referred to as clients) are processed by an interrupt handler component uniformly. The various clients signal interrupts in different manners. For example, some clients signal interrupts in a level-based manner, and some clients signal interrupts in a pulse-based manner. In an embodiment, all interrupts received by the interrupt handler are formed into an event message according to a uniform format regardless of the manner in which the interrupt is signaled. The event message includes all information necessary for a host processor interrupt service routine (ISR) to service the interrupts without reading hardware registers. Event messages are stored in an event buffer for access and handling by the host. The event buffer is managed by the interrupt handler.
