Abstract: Distribution of jobs among compute modules of a cryptocurrency miner is disclosed. A cryptocurrency miner may include a serial bus, compute modules, and a controller. The controller may receive a candidate block, generate jobs based on the candidate block, and distribute the jobs among the plurality of compute modules by issuing a job submit command to the compute modules via the serial bus. The job submit command may comprise block sets that at least partially define the plurality of jobs. The block sets may include a plurality of midstates that correspond to a plurality of message blocks.

Abstract: Multicast reading of compute module registers is disclosed. A cryptocurrency miner comprises a serial bus, compute modules, and a miner controller coupled to the compute modules via the serial bus. The miner controller issues a multicast read command via the serial bus and receives values from respective registers of a first plurality of compute modules. The miner controller may initialize the compute modules with register set configurations that identify respective registers and latencies for returning values from such registers.

Abstract: A cryptocurrency miner includes compute modules and a controller. Each compute module includes a stats store, a manager, and compute engines. The controller is coupled to the compute modules via a serial bus and distributes one or more jobs to the compute modules via the serial bus. Each manager distributes jobs received by its respective compute module among the compute engines of its respective compute module. Each compute engine processes a job and reports a candidate hit found by processing the job. Each manager validates a candidate hit reported by one of the compute engines of its respective compute module, reports the validated candidate hit to the controller; and updates statistical information in the stats store of its respective compute module based on validation of the candidate hit.
