Abstract:
1. A method for processing digital image data comprising: compressing a block of the digital image data to generate a compressed block wherein the compression threshold is (M×N×nrbits)/f wherein M is a width of the block, N is a height of the block, nr bits is a number of bits in a pixel, and f is a compression factor; storing the uncompressed block in an external memory when a number of bits in the compressed block exceed a first compression threshold; and storing the compressed block in the external memory when the number of bits in the compressed block does not exceeds the first compression threshold; and wherein the first compression threshold is one of a plurality of compression thresholds, and wherein the external memory comprises a compressed data buffer corresponding to each of the plurality of compression thresholds and an uncompressed data buffer, and wherein storing the compressed block further comprises: wherein storing the block further comprises:
