  • Patent number: 11113783
    Abstract: Examples described herein relate to a decompression engine that can request compressed data to be transferred over a memory bus. In some cases, the memory bus is a width that requires multiple data transfers to transfer the requested data. In a case that requested data is to be presented in-order to the decompression engine, a re-order buffer can be used to store entries of data. When a head-of-line entry is received, the entry can be provided to the decompression engine. When a last entry in a group of one or more entries is received, all entries in the group are presented in-order to the decompression engine. In some examples, a decompression engine can borrow memory resources allocated for use by another memory client to expand a size of re-order buffer available for use. For example, a memory client with excess capacity and a slowest growth rate can be chosen to borrow memory resources from.

  • Patent number: 11107263
    Abstract: Examples are described here that can be used to enable a main routine to request subroutines or other related code to be executed with other instantiations of the same subroutine or other related code for parallel execution. A sorting unit can be used to accumulate requests to execute instantiations of the subroutine. The sorting unit can request execution of a number of multiple instantiations of the subroutine corresponding to a number of lanes in a SIMD unit. A call stack can be used to share information to be accessed by a main routine after execution of the subroutine completes.

  • Publication number: 20210225066
    Abstract: In some embodiments, a given frame or picture may have different shading rates. In one embodiment in some areas of the frame or picture the shading rate may be less than once per pixel and in other places it may be once per pixel. Examples where the shading rate may be reduced include areas where there is motion and camera defocus, areas of peripheral blur, and in general, any case where the visibility is reduced anyway. The shading rate may be changed in a region, such as a shading quad, by changing the size of the region.
