Abstract
Processing of non-real-time and real-time workloads is performed using discrete pipelines. A first pipeline includes a first shader and one or more fixed function hardware blocks. A second pipeline includes a second shader that is configured to emulate the at least one fixed function hardware block. First and second memory elements store first state information for the first pipeline and second state information for the second pipeline, respectively. A non-real-time workload executing in the first pipeline is preempted at a primitive boundary in response to a real-time workload being dispatched for execution in the second pipeline. The first memory element retains the first state information in response to preemption of the non-real-time workload. The first pipeline is configured to resume processing the subsequent primitive on the basis of the first state information stored in the first memory element.
