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 [login to view URL] 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 as result a bitconin hash/sec low (less than 1MH/s), in that case it is used a fpag 50E cost. Using more complex fpga the result figure pass to 50MH/s, in order to have high performances ity necessary a very large cluster of fpga or asic. The large fpga will have a cost greather than 1000E each, about ASIC I am in cointact with TSMC responsible for Europe and they furnished a figure of 1M to 2 MEuro as function of asic technilogy. Now in order to work with fpga low cost a meddle range PC it will be ok, to work for high end FPGA it is necessary a very expansive PC and a lot of time to compile. For ASIC, the code could be portable but for simulation it will require a very expansive machine. Well, I see yoor bids and I am sure to can give you the better support on this matter but the argument it is very complicated and expansive. I would be very happy to work, but you have to remember what I said before, furthermore consider the development time (you know how bitcoin is very depended by time in this period). Waiting or your comments maurizio stefani please if you like progsel(dot)stefani(at)g$m$a$i$l(dot)com, or mauriziostefani guidonia rome italy for s$k$y$p$e

I have experience in designing FPGAs for Bitcoin mining using the Altera FPGA's. I currently mine Bitcoin so I am aware of the hardware and the capabilities. I have been looking at the open source Litecoin FPGA implementation and have been working on improving it in my spare time. I am up to the challenge and I already have the knowledge necessary to complete the project.
