Latest Patents

One of his latest patents focuses on the "Rasterization of Compute Shaders." This patent describes compiler algorithms that partition a compute shader program into maximal-size regions, known as thread-loops. The algorithms can eliminate original barrier-based synchronization while ensuring that the transformed shader program remains semantically equivalent to the original. This advancement allows for optimization through existing compiler technology and enables efficient execution by CPU threads. Additionally, a Dispatch call can be load-balanced on a CPU by assigning single or multiple CPU threads to execute thread blocks without overloading the CPU.

Another notable patent is centered on "Scalar Optimizations for Shaders." This patent outlines optimizations of thread loop intermediate representation (IR) code. One embodiment features an algorithm that computes sets of temporary variables loaded at the beginning of a thread loop and stored upon exit. Another embodiment reduces the size of a thread loop trip for cases where a compute shader is executed by a single thread. Furthermore, compute shader thread indices are cached to avoid excessive divisions, enhancing execution speed.
