An electronic system for calculating and mining digital currency using circuits optimized for efficient utilization of hash engine circuitry by determining an effective hash clock operational frequency for one or more hash engines in the system. The hash engines can be evaluated to determine a maximum operational frequency for a given error threshold. The hash engines can also be partitioned into one or more hash engine groups to allow different groups to operate at different overclocked frequencies.

Overclocking system for digital currency mining and method of operation

Methods, circuits, apparatus, and systems for managing multi-phase clocking signals for integrated circuit devices are provided. In one aspect, an integrated circuit device includes: a clock signal generator configured to generate a reference clock signal and a plurality of processing units coupled to the clock signal generator. At least one of the plurality of processing units includes: a phase generator configured to selectively generate at least two sets of multi-phase clock signals based on the reference clock signal and corresponding control signals, the at least two sets of multi-phase clock signals having different respective frequencies; and a computation unit configured to perform at least one computing function based on a selected one of the at least two sets of multi-phase clock signals.

Managing multi-phase clock signals for integrated circuit devices

An electronic system for calculating and mining digital currency using circuit layout optimized for power consumption, performance level, and integrated circuit surface area. A circuit simulation system simulates and evaluates circuit layouts retrieved from a circuit database to identify circuit parameters to compare against threshold values. The circuit simulation varies operational parameters of the circuits simulated to evaluate the active circuit parameters. The operational parameters include voltage levels, clock frequencies, thermal characteristics, and layout characteristics of dedicated components and sub-modules. The active circuit parameters include the effective hash rate, power, performance, and surface area.

Circuit optimization for digital currency mining system and method of operation

A local buffer is integrated with a witness generator and a proof generator on a cryptographic processor and is separate from host memory accessed by a host processor operating with the cryptographic processor in a proving computing system. The witness generator: receives, from software program running on the host processor, compiled code of a zero-knowledge-proof (ZKP) program and specific input to the ZKP program; executes the ZKP program by way of executing the compiled code; records specific output generated from the ZKP program with the specific input, intermediate variable values, and the specific input, as a specific witness of executing the ZKP program; stores the specific witness in the local buffer. The proof generator: receives, from the software program running on the host processor, a proving key; accesses the specific witness in the local buffer; generates a specific zero-knowledge proof for executing the ZKP program with the specific input.
