A hardware accelerator receives a request to decompress a data stream that includes multiple deflate blocks and multiple deflate elements compressed according to block-specific compression configuration information. The hardware accelerator identifies a commit point that is based upon an interruption of a first decompression session of the data stream and corresponds to one of the deflate blocks. As such, the hardware accelerator configures a decompression engine based upon the corresponding deflate block's configuration information and, in turn, recommences decompression of the data stream at an input bit location corresponding to the commit point.
