Patent number: 9715539Abstract: 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.Type: GrantFiled: April 15, 2016Date of Patent: July 25, 2017Assignee: International Business Machines CorporationInventors: Kanak B. Agarwal, Damir A. Jamsek, Andrew K. Martin, Reiner Rieke, Joerg-Stephan Vogt, Gunnar von Boehn

Patent number: 9559857Abstract: A preprocessing unit includes a data receiver to receive a data packet containing packet information, application data, and application data information, a relevance checker to determine relevance of the data packet in dependence on the packet information, an output module to output preprocessor output data, and a first controller to control output of preprocessor output data in dependence on the relevance of the data packet. In order to discard redundant data, thereby reducing the load of the memory, bus, and CPU of the computer system, the preprocessing unit further comprises a redundancy checker to determine redundancy of the application data preferably and a second controller to control output of preprocessor output data in dependence on the redundancy of the application data.Type: GrantFiled: June 23, 2014Date of Patent: January 31, 2017Assignee: International Business Machines CorporationInventors: Gunnar Von Boehn, Reiner Rieke, Joerg-Stephan Vogt

Patent number: 9176977Abstract: Embodiments relate to providing a data stream interface for offloading the inflation/deflation processing of data to a stateless compression accelerator. An aspect includes transmitting a request to inflate or deflate a data stream to a compression accelerator. The request may include references to an input buffer for storing input data from the data stream, an output buffer for storing processed input data, and a state data control block for storing a stream state. The stream state is provided to the compression accelerator to continue processing the data stream responsive to the request being a subsequent request. The compression accelerator is instructed to store a current stream state in the state data control block responsive to the request being a non-final request. Accordingly, the current stream state is received from the compression accelerator responsive to the request being a non-final request. The processed input data is received from the compression accelerator.Type: GrantFiled: September 30, 2014Date of Patent: November 3, 2015Assignee: International Business Machines CorporationInventors: Hartmut Droege, Thomas Fuchs, Frank Haverkamp, Reiner Rieke, Michael Ruettger, Anthony T.
