Abstract
Shader processing units for a graphics processing unit that are configured to execute one or more ray tracing shaders that generate ray data associated with one or more rays. The ray data for a ray includes a plurality of ray data elements. The shader processing unit comprises local storage, and store logic. The store logic is configured to receive, as part of a ray tracing shader, a ray store instruction that comprises: (i) information identifying a store group of a plurality of store groups, each store group of the plurality of store groups comprising one or more ray data elements of the plurality of ray data elements, and (ii) information identifying one or more ray data elements of the identified store group to be stored in an external unit). In response to receiving the ray store instruction, the store logic retrieves the identified ray data elements for one or more rays from the storage. The store logic then sends one or more store requests to an external unit which cause the external unit to store the identified ray data elements for the one or more rays.
