Abstract: Apparatuses including general-purpose graphics processing units and graphics multiprocessors that exploit queues or transitional buffers for improved low-latency high-bandwidth on-die data retrieval are disclosed. In one embodiment, a graphics multiprocessor includes at least one compute engine to provide a request, a queue or transitional buffer, and logic coupled to the queue or transitional buffer. The logic is configured to cause a request to be transferred to a queue or transitional buffer for temporary storage without processing the request and to determine whether the queue or transitional buffer has a predetermined amount of storage capacity.

Abstract: Described herein is a graphics processor configured to perform time based frame generation via a temporally aware machine learning model that enables the generation of a frame at a target timestamp relative to the render times of input frames. For example, for an extrapolated frame generated by the temporally aware machine learning model, a low relative timestamp would indicate that the extrapolated frame will appear close in time after the final frame in a sequence of frames and should be relatively close in appearance to the final frame. A higher relative timestamp would indicate that the extrapolated frame should depict a greater degree of evolution based on the optical flow.
