摘要： An apparatus comprises a hardware accelerator coupled to a memory. The hardware accelerator comprises one or more decompression units. The one or more decompression units are reconfigurable. The hardware accelerator may be a field-programmable gate array. The hardware accelerator may also comprise one or more reconfigurable scanner units. The one or more decompression units, in the aggregate, are operative to decompress one or more rows of a database at a bus speed of the coupling between the hardware accelerator and the memory. Two or more decompression units are operative to decompress two or more rows of a database in parallel. The apparatus allows for hardware accelerated row decompression.

摘要： Techniques are provided for hardware-accelerated relational joins. A first table comprising one or more rows is processed through a hardware accelerator. At least one join column in at least one of the one or more rows of the first table is hashed to set at least one bit in at least one bit vector. A second table comprising one or more rows is processed through a hardware accelerator. At least one join column in at least one of the one or more rows of the second table is hashed to generate at least one hash value. At least one bit vector is probed using the at least one hash value. A joined row is constructed responsive to the probing step. The row-construction step is performed in the hardware accelerator.

摘要： Generating a data feed specific parser circuit is provided. An input of a number of bytes of feed data associated with a particular data feed that the data feed specific parser circuit is to process is received. A feed format specification file that describes a data format of the particular data feed is parsed to generate an internal data structure of the feed format specification file. A minimum number of parallel pipeline stages in the data feed specific parser circuit to process the number of bytes of feed data associated with the particular data is determined based on the generated internal data structure of the feed format specification file. Then, a description of the data feed specific parser circuit with the determined number of parallel pipeline stages is generated.
