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 given.
I need an engineer for design and programming PCB boards (ASIC) for SHA256 + Scrypt Hashing. You should design and test PCB with ASIC chip. Programming this chips for SHA256 and scrypt alogorithm ([login to view URL]). Chips will be prebuild from Altera or Xillinx manufacturers. You can use any open source sheets (Open)
I need to get a prototype like :

If the design work, u can get more projects + bonus
This project work arroud bitcoin
PCB bords must get the detail below :
1000GH/s per device.
28nm Standard ASIC
Maximum 400w

This bord must work with usb2 with adequated Driver
Mining Software compatibility
EasyMiner software is provided for Android, Windows & Linux operating systems.
BFGminer - Open source available
CGminer - Open source available
BitMinter - Java Client
U can get information fro the driver:

First steps:
1) Design the PCB board to mining BTC and LTC with sha256 and scrypt | Chips will be prebuild from Altera or Xillinx manufacturers
and the next step we will test the design and get the prototype
Are you OK for this challenge ?
I have read the document that the project description comes from.
I have been interested in ASIC bitcoin mining for sometime.
If your interested, i will draw up an architecture proposal, and I will implement it in verilog as well as design a pcb for the project
