Abstract :
This paper proposes a low bandwidth HD1080@60fps JPEG-XR transform design to solve the huge memory access problem induced by doing Photo Overlap Transform (POT) in JPEG-XR. Three low bandwidth techniques are proposed to decrease the amount of data access in the overlapping area between MBs when doing the POT, especially in the POT-2 mode. The proposed design can reduce 72% memory bandwidth when compared to the conventional method. At operating frequency of 250MHz, the proposed design could support the real-time processing for videos with resolution up to HD1080@60fps.
