Abstract
A multi-resolution cache includes a first, second and third cache segments the first segment having a first resolution and the second and third segments having a second resolution, the second resolution less than the first resolution, the first and third cache segments communicatively coupled to an off-chip memory, the first and third cache segments configured to each receive a cache line of data having the first and second resolutions, a fourth and fifth cache segments having the second resolution, a first downscaler communicatively coupled to the first and fourth cache segments configured to reduce the resolution when a first resolution cached data is shifted from the first cache segment to the fourth cache segment, a first upscaler communicatively coupled to the all cache segments that have the second resolution, and is configured to increase the reduced resolution cached data to the first resolution and output it.
