Patent number: 11221932Abstract: Methods and systems for monitoring the integrity of a graphics processing unit (GPU) are provided. The method comprises the steps of determining a known-good result associated with an operation of the GPU, and generating a test image comprising a test subject using the operation of the GPU, such that the test subject is associated with the known-good result. The test image is written to video memory, and the known-good result is written to system memory. Subsequently, the test subject from the test image is transferred from video memory to system memory. The test subject in the system memory is compared with the known-good result in system memory. If the test subject does not match the known-good result, then a conclusion is drawn that the integrity of the GPU has been compromised.Type: GrantFiled: August 11, 2020Date of Patent: January 11, 2022Assignee: Channel One Holdings Inc.Inventors: Stephen Viggers, Tomislav Malnar, Sherwyn R. Ramkissoon, Gregory J. Szober, Aidan Fabius, Kenneth Wenger, John McCormick

Patent number: 11164496Abstract: Methods and systems for multiple-buffered display rendering without the use of hardware or software interrupts. In a first repeating process, a processor writes data for a frame a selected frame buffer and, upon completion of the frame, a swap buffer signal is transmitted. In response to the swap buffer signal, the GPU updates a memory register of the display controller to indicate that the selected frame buffer can be used in the next display synchronization interval. In a separate repeating process, the display controller monitors memory register and, in a display synchronization interval, identifies the frame buffer to use for display.Type: GrantFiled: December 31, 2019Date of Patent: November 2, 2021Assignee: Channel One Holdings Inc.Inventor: Tomislav Malnar

Patent number: 10540738Abstract: Methods, systems, and computer-readable media for monitoring a graphics processing unit (GPU) of a host computer system, including providing at least one test seed and at least one subsystem command to the GPU; receiving at least one test result from the GPU in response to providing the at least one test seed and at least one subsystem command to the GPU; and if the at least one test result does not correspond to at least one expected result, identifying the GPU as being in an undesired state. The subsystems to be tested may be a subset of all subsystems. The determination of subsystems to be tested may be determined in real-time, based on graphical application instructions. The subsystems to be tested may also be pre-determined.Type: GrantFiled: June 4, 2019Date of Patent: January 21, 2020Assignee: Channel One Holdings Inc.Inventors: Stephen Viggers, Tomislav Malnar, Sherwyn R.

Publication number: 20170116702Abstract: A system, method, and computer-readable medium are provided for translating OpenGL API calls to operations in a Vulkan graphics driver using an OpenGL-on-Vulkan driver architecture.
