A processing device comprising compression circuitry to: determine a compression configuration to compress source data; generate a checksum of the source data in an uncompressed state; compress the source data into at least one block based on the compression configuration, wherein the at least one block comprises: a plurality of sub-blocks, wherein the plurality of sub-block includes a predetermined size; a block header corresponding to the plurality of sub-blocks; and decompression circuitry coupled to the compression circuitry, wherein the decompression circuitry to: while not outputting a decompressed data stream of the source data: generate index information corresponding to the plurality of sub-blocks; in response to generating the index information, generate a checksum of the compressed source data associated with the plurality of sub-blocks; and determine whether the checksum of the source data in the uncompressed format matches the checksum of the compressed source data.
