摘要
Techniques are disclosed relating to dispatching compute work from a compute stream. In some embodiments, workgroup batch circuitry is configured to select (e.g., in a single clock cycle) multiple workgroups to be distributed to different shader circuitry. In some embodiments, iterator circuitry is configured to determine next positions in different dimensions at least partially in parallel. For example, in some embodiments, first circuitry is configured to determine a next position in a first dimension and an increment amount for a second dimension. In some embodiments, second circuitry is configured to determine at least partially in parallel with the determination of the next position in the first dimension, next positions in the second dimension for multiple possible increment amounts in the second dimension. In some embodiments, this may facilitate a configurable number of workgroups per batch and may increase performance, e.g., by increasing the overall number of workgroups dispatched per clock cycle.
