Patents by Inventor Lloyd A. Cunningham

Lloyd A. Cunningham has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10664943
    Abstract: The disclosed concepts provide a method to generate and use a compound shader object. A compound shader object includes a shader's intermediate representation (IR) and one or more binary modules; each binary module configured to execute on one type of graphics processing unit (GPU) with a specific input state. One method includes receiving, through a public application programming interface (API), a request to execute a shader from an user-level application. At the framework level, if the request corresponds to one of the prior compiled binary modules, that module may be passed to a GPU for immediate execution via a system private interface. If the request does not correspond to one of the binary modules, the shader's IR module may returned to the requesting user-level application (which module would then have to be compiled before it may be sent to the GPU).
