Abstract: Apparatus and method for a decompression hardware copy engine with efficient sequence overlapping copy. For example, one embodiment of an apparatus comprises: a plurality of processing cores, one or more of the plurality of processing cores to execute program code to produce a plurality of literals and sequences from a compressed data stream; and decompression acceleration circuitry to generate a decompressed data stream based on the plurality of literals and sequences, the decompression acceleration circuitry comprising: a sequence pre-processor circuit to process batches of sequences of the plurality of sequences and generate a plurality of copy instructions, the sequence pre-processor circuit to merge multiple copy operations corresponding to multiple sequences into a merged copy instruction; and a copy engine circuit to execute the copy instructions to produce the decompressed data stream.
