Abstract
A method for decoding run-length encoded (RLE) data includes the steps of receiving the RLE data and storing a predetermined value (e.g., zero) in each of a plurality of consecutively-accessible storage locations of a buffer. The method further includes writing a first value different than the predetermined value to a first storage location based on the RLE data, jumping over (i.e., skipping) a number of the consecutively-accessible storage locations from the first storage location to a next storage location based on the RLE data, and writing a next value different than the predetermined value to the next storage location based on the RLE data. In the case of JPEG, the values stored in the storage locations of the buffer are quantized coefficients associated with a block of image data. A run-length decoder is also described.
