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.

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.
A graphics processing system comprising a graphics processing unit configured to perform safety-critical rendering and a safety controller for the graphics processing system, in which:
- the graphics processing system is configured to receive graphical data for safety-critical rendering at the graphics processing unit;
- the safety controller is configured to schedule, in accordance with a reset frequency, a plurality of resets of the graphics processing unit;
- the graphics processing unit is configured to render the graphical data;
- and
- the safety controller is configured to cause the plurality of resets of the graphics processing unit to be performed commensurate with the reset frequency.
A non-transitory computer readable storage medium having stored thereon a computer readable dataset description of an integrated circuit that, when processed in an integrated circuit manufacturing system, causes the integrated circuit manufacturing system to manufacture a graphics processing system comprising a graphics processing unit configured to perform safety-critical rendering and a safety controller for the graphics processing system, in which:
- the graphics processing system is configured to receive graphical data for safety-critical rendering at the graphics processing unit;
- the safety controller is configured to schedule, in accordance with a reset frequency, a plurality of resets of the graphics processing unit;
- the graphics processing unit is configured to render the graphical data;
- and
- the safety controller is configured to cause the plurality of resets of the graphics processing unit to be performed commensurate with the reset frequency.
