MINIMIZING LATENCY FROM PERIPHERAL DEVICES TO COMPUTE ENGINES

摘要

Methods, systems, and computer program products are provided for minimizing latency in a implementation where a peripheral device is used as a capture device and a compute device such as a GPU processes the captured data in a computing environment. In embodiments, a peripheral device and GPU are tightly integrated and communicate at a hardware/firmware level. Peripheral device firmware can determine and store compute instructions specifically for the GPU, in a command queue. The compute instructions in the command queue are understood and consumed by firmware of the GPU. The compute instructions include but are not limited to generating low latency visual feedback for presentation to a display screen, and detecting the presence of gestures to be converted to OS messages that can be utilized by any application.
