  • Data processing systems
    Patent number: 10719632
    Abstract: A data processing system includes a host processor that executes an operating system and an accelerator operable to process data under the control of the operating system executing on the host processor. The accelerator can be switched between a normal mode of operation and a protected mode of operation in which the side channel information that can be provided by the accelerator to the host processor is restricted. The data processing system also includes a mechanism for switching the accelerator from its normal mode of operation to the protected mode of operation, and from its protected mode of operation to the normal mode of operation.

  • Multiple GPU graphics processing system
    Patent number: 10475147
    Abstract: A graphics processing system comprises a pair of graphics processing units that are connected to each other via communications bridges that can allow communication between the connected graphics processing units. One of the graphics processing units is operable to act as a master graphics processing unit controlling graphics processing operations on the other graphics processing unit which is operable as a slave graphics processing unit to perform graphics processing operations under the control of the master graphics processing unit. Each graphics processing unit of the pair of graphics processing units is also capable of operating in a standalone mode, in which the graphics processing unit operates independently of the other graphics processing unit to perform a graphics processing task.
