Raster to block conversion in a compressed domain

摘要

A system for raster to block conversion in a compressed domain may include a raster to block encoder, a raster to block decoder, and a memory partitioned into a number of memory stripes having widths of a number of bits. The raster to block encoder may be configured to receive image information associated with pixels of an image in raster order, compress the image information associated with the pixels of the image to generate compressed bits that correspond to at least one of memory stripes, and write the compressed bits to the at least one of the memory stripes. The raster to block decoder may be configured to read, from at least one of the memory stripes of the memory, a number of the compressed bits that correspond to at least one block, and decode the number of the compressed bits to generate the at least one block.

1. A method for raster to block conversion in a compressed domain, the method comprising:
determining a number of memory stripes of a memory that correspond to an image based at least on a size of the image, the memory stripes having memory stripe widths of a number of bits; receiving image information associated with pixels of the image in raster order; compressing the image information associated with the pixels of the image in the raster order to generate compressed bits; writing the compressed bits to at least one of the memory stripes that corresponds to the pixels from which the compressed bits were generated; reading, from the at least one of the memory stripes of the memory, a number of the compressed bits that correspond to at least one block; and decoding the number of the compressed bits to generate the at least one block.
