US 2026/0065409 A1 · CACHE EFFICIENT FETCHES OF VERTEX BUFFER OBJECTS

Abstract

This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for improving the cache efficiency for fetching vertex buffer objects (VBOs). A graphics processor may determine that a logically contiguous segment of a vertex attribute buffer comprising a plurality of VBOs that include a first VBO element and a second VBO element is capable of being stored in a cache line (CL). The graphics processor may store the logically contiguous segment in the CL based on the determination. The graphics processor may retrieve the second VBO element from the CL after storage of the logically contiguous segment in the CL. The graphics processor may process the retrieved second VBO element in at least one of a binning pass or a rendering pass. The graphics processor may output an indication of the processed second VBO element.

Dependent claims

An apparatus for graphics processing, comprising:

a memory;
and
a processor coupled to the memory and, based at least in part on information stored in the memory, the processor is configured to:
determine that a logically contiguous segment of a vertex attribute buffer comprising a plurality of vertex buffer objects (VBOs) that include a first VBO element and a second VBO element is capable of being stored in a cache line (CL);
store the logically contiguous segment comprising the first VBO element and the second VBO element in the CL based on the determination that the logically contiguous segment is capable of being stored in the CL;
retrieve the second VBO element from the CL after storage of the logically contiguous segment in the CL;
process the retrieved second VBO element in at least one of a binning pass or a rendering pass;
and
output an indication of the processed second VBO element.
