Coding, transcoding and iterative filtering methods and apparatus are described wherein a 2D FIFO is used to implement CACLA processing, and wherein the processing methods are block-oriented. A block-by-block processed input image or input coded image, which is delayed in an arbitrary number of lines and columns, is provided such that the output image is produced in a block-by-block schedule at a reduced or minimal memory access and memory size cost. A 2D FIFO which is memory-efficient in image block coding and decoding applications is described. The 2D FIFO has an associated scheduling mechanism for enabling delay of a block-by-block coded input signal, such as an image, in an arbitrary number of lines and columns, such that the output image is produced in a block-by-block schedule.
A method of coding an input signal or decoding an input coded signal, wherein the input signal or the input coded signal is in the form of a plurality of blocks arranged in rows and columns, and wherein coding of the input signal or decoding of the input coded signal includes filtering each of the plurality of block to form an output block, the method comprising:
A coder configured to code an input signal or decode an input coded signal, wherein the input signal or the input coded signal is in the form of a plurality of blocks, wherein coding of the input signal or decoding of the input coded signal includes performing a transform on each of the blocks to form an output block, the coder comprising:
