Abstract: Aspects of the disclosure provide a method and device for storing an input image into a memory. The disclosure describes allocating one or more frame buffers in the memory. The disclosure further describes dividing the input image into access units corresponding to subsets of the input image and allocating a main portion and a secondary portion in the frame buffer for each of the access units, wherein at least one of the secondary portions is not sequentially located after its respective main portion within the frame buffer. The disclosure also describes compressing the access units into compressed access units and storing each of the compressed access units into its respective main portion, and if a size of the compressed access unit exceeds a size of the main portion, then storing a remainder of the compressed access unit into its respective secondary portion.
