Abstract: A processing unit includes traversal recursion circuitry that performs, on behalf of a software shader, at least some of the requisite actions for traversing selected types of nodes of the acceleration structure. In response to identifying a first node of a raytracing acceleration structure is of a first type, the processing unit provides an intersection result for the first node to recursion circuitry. In response to the intersection result for the first node, the processing unit performs a traversal operation for the raytracing acceleration structure at the recursion circuitry.

Abstract: In response to receiving a request for an atomic operation on a first element of a vector comprising a first address and a first data value, a processing system determines a request history associated with the first element. The processing system selectively alters the first request, based on the request history and the first data value.
