Bitcoin Asic design - repost 2

After recalling the basic algorithms published by NIST for implementing the hash functions SHA-256 (384, 512), a basic circuit characterized by a cascade of full adder arrays is given. Implementation options are discussed and two methods for improving speed are exposed: the delay balancing and the pipelining. An application of the former is first given, obtaining a circuit that reduces the length of the critical path by a full adder array. A pipelined version is then given, obtaining a reduction of two full adder arrays in the critical path. The two methods are afterwards combined and the results obtained through hardware synthesis are exposed, where a comparison between the new circuits is also [url removed, login to view] need an engineer for design and programming PCB boards (ASIC) for SHA256 + Scrypt Hashing.

HI, I partecipated to three or four bid on bitcon. A couple was in Europe and one was in US. I have the bticon algorithm developed on vhdl and partially tested on altera fpga. But, the result on low fpga level have Plus
