It is a temporal upscaler, meaning it combines information from multiple frames to generate output.
Conversely, spatial upscalers work on a frame-by-frame basis and generally have lower requirements.
Early test results look promising.

According to Arm, the relative framerate at 2x upscaling was53 percent highercompared to the rig’s native performance.
Arm ASR also delivers significant power savings.
Reduced power consumption also means devices run cooler and will be more comfortable in the hand.
Arm’s new upscaler has a lot going for it, and not just in terms of performance.
Best yet, Arm is sharing the tech with the community under an MIT open-source license.
Interested parties are invited toreach outto become early adopters.
We can’t wait to see what developers are able to do with it.
Arm is not the first to develop an upscaler for mobile devices.
