Abstract: A trusted content usage monitor for monitoring content usage is provided. A unique identifier generation unit generates a unique identifier indicative of content being rendered and a packet generator generates a trusted packet comprising the unique identifier. The trusted packet is trust signed by the trusted content usage monitor, so that it can be trusted by its recipient. The trusted content usage monitor has at least one mode of operation in which content rendering cannot be decoupled from operation of the unique identifier generation unit, so that generated packets can be trusted as truly indicative of content usage.

Abstract: Simulation of execution of a processing workload by a target hardware device is provided by providing workload data specifying the processing workload, passing the workload data to both a primary partial simulation and a complementary partial simulation that run in parallel and acquire input data from different levels of abstraction of the target hardware and then simulating execution of the processing workload using a primary partial simulation to generate primary partial result state data and using the complementary partial simulation to generate complementary partial result state data. The target hardware device may be a graphics processing unit and the workload data may specify the processing to be performed in a hardware independent form, such as, for example, OpenGL ES. The host system supporting the simulation may include a graphics processing unit serving to provide the complementary partial simulation due to its own execution of the workload data.
