Abstract: Systems and methods for improved texture mapping and graphics processing are described. According to an example implementation, whole or parts of texture blocks are prefetched to an intermediate cache by a processing unit so that the same processing unit or another processing unit can subsequently obtain the prefetched texture block from the intermediate cache. Moreover, in some example implementations, control circuitry associated with the intermediate cache may throttle prefetch requests in order to avoid the memory system and/or the interconnect system receiving excessive amounts of prefetch requests. Additionally, in some implementations, deduplication of prefetch requests can be performed at the intermediate cache and/or the processing unit. Some implementations also include an efficient technique for calculating the address of the next texture block to be prefetched.

Abstract: Secure rendering system that creates ray tracing samples with obfuscated positions, so that images can only be viewed by an authorized consumer able to recover the sample positions. Obfuscation of ray directions is integrated into the rendering process, for example by incorporating encryption into a lens shader. The rendering system never stores or transmits an image without obfuscating positions, so even the rendering system cannot see the image it is rendering. Embodiments may use public key cryptography, so that encryption of sample positions is done with a public key, and only the owner of the secret private key can view the rendered image. Since keys are asymmetric, the rendering system cannot decrypt the obfuscated samples. Piracy of rendered images is therefore mitigated. Some compositing operations may be performed on the secure rendering output prior to decrypting sample positions; for example, colors may be modified globally or for selected objects.

Abstract: A method of directly modifying ray tracing samples generated by a ray tracing renderer. Modifications to samples may be made after rendering and before rasterizing, in contrast to typical compositing workflows that manipulate pixels of a rasterized image. Modifications may be based on user input. Rasterization may be performed afterwards at any desired resolutions, for example to adapt to different displays. Samples may be tagged with object identities, facilitating object selection without the need for object masks. Pseudo-random ray patterns typically used by renderers may be supported directly. Many operations may be performed directly on samples, including color changes, object repositioning, and merging of samples from different scenes. Secure samples with scrambled ray directions may be modified directly.
