US 2016/0364830 A1 · ASYNCHRONOUS TRANSLATION OF COMPUTER PROGRAM RESOURCES IN GRAPHICS PROCESSING UNIT EMULATION

Abstract

Resource processing during run time can be performed asynchronously from emulation of an application by a central processing unit. For example, an emulator can include a main processing thread that performs emulation processes. In response to encountering a shader, or other resource, to be processed, the emulator can invoke a separate asynchronous thread to perform such processing. Processed resources, such as translated shaders and generated textures, can be stored in a cache. In response to a command that uses a resource, such as a draw command that invokes a shader or other resource, the emulator can use the processed resource in the cache. If the processed resource is not in the cache, the emulator can skip processing the command that uses the resource. If processed resources can be obtained from other sources and loaded in the cache, processing of resources by the emulator can be eliminated.

Dependent claims

A computer configured to emulate execution of a graphics application for a first graphics processing unit, the computer comprising:

a second graphics processing unit;
storage;
one or more central processing units configured to execute an emulator application, the emulator application configuring the computer to:
convert first commands for the first graphics processing unit, generated by execution of the graphics application by the emulator application, to second commands that instruct the second graphics processing unit;
manage a resource cache including translated resources for the second graphics processing unit for a plurality of resources;
and
in response to a first command being a draw command using a resource, and a determination that a translated resource for the second graphics processing unit corresponding to the resource used by the draw command is not in the resource cache, skip rendering a second command corresponding to the draw command and continue processing by the emulator application.
