Abstract
A method for processing digital image data is provided that includes compressing a block of the digital image data to generate a compressed block, storing the compressed block in an external memory when a number of bits in the compressed block does not exceed a first compression threshold, and storing the block in the external memory when the number of bits in the compressed block exceeds the first compression threshold.
