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.
