Surface Instructions for Multi-Dimensional Graphics Memory Access

The patent introduces surface instructions that enable the GPU computing features to perform both traditional graphics processing and compute applications. These instructions provide universal access to multi-dimensional formatted graphics surface memory, allowing compute application programs to read and write surface data directly using the same hardware architecture, thus achieving multi-functionality without requiring separate memory access paths

The patent introduces surface instructions as an intermediary mechanism between compute application programs and graphics surface memory. These instructions act as a bridge that translates compute program memory access requests into appropriate graphics surface memory accesses, enabling compute applications to interact with graphics memory without requiring direct configuration of the graphics processing pipeline

The patent implements self-service by embedding the address conversion and format transformation logic within the GPU hardware itself. The surface instructions automatically handle the conversion from compute program memory addresses to graphics surface memory addresses and transform data formats as needed, eliminating the need for complex software-based address translation and format conversion mechanisms

The patent utilizes parameter changes by allowing the surface instructions to dynamically adjust memory access parameters based on the graphics surface configuration. The hardware automatically modifies address calculations and data formatting parameters according to the surface's dimensions, format, and layout, simplifying the compute program while the hardware handles the parameter transformations
