Abstract: A method and engine for hash calculation, the method comprising receiving data blocks via an input module, providing clock cycles by a clock module, calculating a hash from a received data block by a process module including a data pipeline and a state pipeline, the hash calculation comprising: receiving an input data block to the data pipeline, calculating, in every other clock cycle of the clock module, an induced data block based on the previous data block, and performing a stage of the state pipeline in each clock cycle of the clock module, in which a state is calculated based on input from the data pipeline, and outputting the hash via an output module.

Abstract: A method and engine for hash calculation, the method comprising receiving data blocks via an input module, providing clock cycles by a clock module, calculating a hash from a received data block by a process module including a data pipeline and a state pipeline, the hash calculation comprising: an input data block to the data pipeline, the data block includes a sequence of data words including X data words, wherein X is a known number, calculating, in every other clock cycle of the clock module, an new data word based on the last calculated X data words, and performing a stage of the state pipeline in each clock cycle of the clock module, in which a state is calculated based on input from the data pipeline, the input includes the last calculated X data words, and outputting the hash via an output module every predetermined number of clock cycles.
