Abstract
A data processing system in which a host processor prepares command streams for causing an accelerator of the data processing system to perform processing tasks for an application executing on the host processor, each command stream including a sequence of commands for implementation by the accelerator. When a request for processing includes protected content, the host processor includes within a command for a command stream, an indication that a subsequent sequence of one or more command(s) within that command stream associated with the protected content is to be implemented by the accelerator in a protected mode of operation. Then, when that command is executed, the accelerator initiates or requests a switch into the protected mode of operation.
