Patent number: 11276223Abstract: Described herein is a merged data path unit that has elements that are configurable to switch between different instruction types. The merged data path unit is a pipelined unit that has multiple stages. Between different stages lie multiplexor layers that are configurable to route data from functional blocks of a prior stage to a subsequent stage. The manner in which the multiplexor layers are configured for a particular stage is based on the instruction type executed at that stage. In some implementations, the functional blocks in different stages are also configurable by the control unit to change the operations performed. Further, in some implementations, the control unit has sideband storage that stores data that “skips stages.” An example of a merged data path used for performing a ray-triangle intersection test and a ray-box intersection test is also described herein.Type: GrantFiled: December 13, 2018Date of Patent: March 15, 2022Assignee: Advanced Micro Devices, Inc.Inventors: Skyler Jonathon Saleh, Jian Mao
