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.

Methods for allocating information to system resources using improved mapping

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.
