Abstract
Systems for hardware-accelerated lossless data compression are described. At least some embodiments include data compression apparatus that includes a plurality of hash memories each associated with a different lane of a plurality of lanes (each lane including data bytes of a data unit being received by the compression apparatus), an array including array elements each including a plurality of validity bits (each validity bit within an array element corresponding to a different lane of the plurality of lanes), control logic that initiates a read of a hash memory entry if a corresponding validity bit indicates that said entry is valid, and an encoder that compresses at least the data bytes for the lane associated with the hash memory comprising the valid entry if said valid entry comprises data that matches the lane data bytes.
