HashFast tapes out GN ASIC on TSMC’s 28HPM process

HashFast Technologies has taped out Golden Nonce (GN) Bitcoin network transaction verification ASIC on TSMC’s 28HPM process. The design simulation has performed more than 400 billion double-SHA256 hashing operations per second (GHash/s), while consuming less than 0.6 W/GHash/s at nominal clock rate. The GN chip will be fabricated at TSMC’s 28nm GIGAFAB foundry in Taiwan. HashFast said it has already increased the initial planned production volume of the GN chip to address strong pre-order demand. Key features of the design include a modular architecture, a fault-tolerant physical layout to allow for maximum silicon yield, and an ability to be overclocked for greater performance and underclocked for greater efficiency. Its use of on-die thermal controls allows operation at its maximum performance given the capacity of the cooling system deployed with it. The first product to house this processor is Baby Jet mining systems, after the initial batch of GN chips is produced and tested, Baby Jet to begin shipping in volume. “The rapid development and tape out of the GN chip is another testimony to the power of our Perseus design management system,” says Josh Lee, Uniquify’s founder and chief executive officer (CEO). “With Perseus, we were able to go from first RTL code to final tape out in under three months, an exceptional performance for any ASIC design program, le...
