Abstract: An electronic device includes a memory usage identification circuit and a system-level cache (SLC). The memory usage identification circuit obtains a memory usage indicator that depends on memory usage of a storage space allocated in a system memory at which memory access is requested by a physical address. The SLC includes a cache memory and a cache controller. The cache controller performs cache management upon the cache memory according to the physical address and the memory usage indicator.

Abstract: A technique, as well as select implementations thereof, pertaining to dynamic adjustment of video frame sampling rate is described. The technique may involve receiving a first video signal comprising a first plurality of video frames and determining a frame rate of the first plurality of video frames. The technique may also involve adjusting a sampling rate according to the determined frame rate of the first plurality of video frames. The technique may further involve sampling the first plurality of video frames at the adjusted sampling rate. The technique may additionally involve generating a second video signal comprising a second plurality of video frames based on the sampled first plurality of video frames.
