Abstract
A method of performing safety-critical rendering at a graphics processing unit within a graphics processing system, the method comprising: receiving, at the graphics processing system, graphical data for safety-critical rendering at the graphics processing unit; scheduling at a safety controller, in accordance with a reset frequency, a plurality of resets of the graphics processing unit; rendering the graphical data at the graphics processing unit; and the safety controller causing the plurality of resets of the graphics processing unit to be performed commensurate with the reset frequency.
Claims20
A method of rendering an instrument cluster, using a tile-based rendering technique, at a graphics processing unit comprising a plurality of processing elements, the method comprising:
- scheduling, in accordance with a reset frequency, a plurality of resets of one or more processing elements of the plurality of processing elements that are used for rendering tiles that include safety critical information;
- and
- causing the plurality of resets to be performed commensurate with the reset frequency.
A graphics processing system comprising:
- a graphics processing unit configured to render an instrument cluster, using a tile-based rendering technique, the graphics processing unit comprising a plurality of processing elements;
- and
- a safety controller for the graphics processing system, the safety controller being configured to:
- schedule, in accordance with a reset frequency, a plurality of resets of one or more processing elements of the plurality of processing elements that are configured to be used for rendering tiles that include safety critical information;
- and
- cause the plurality of resets to be performed commensurate with the reset frequency.
A non-transitory computer readable storage medium having stored thereon computer readable instructions that, when executed at a computer system, cause the computer system to perform a method of rendering an instrument cluster, using a tile-based rendering technique, at a graphics processing unit comprising a plurality of processing elements, the method comprising:
- scheduling, in accordance with a reset frequency, a plurality of resets of one or more processing elements of the plurality of processing elements that are used for rendering tiles that include safety critical information;
- and
- causing the plurality of resets to be performed commensurate with the reset frequency.
