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.

I have experience of 14+ years of Electronic design , Microchip programming ,PCB design & PCB manufacturing process. I have 8 years of experience working with Celestica - PCB assembly company and nearly 6 years in Samsung Electronics as PCB assembly Engineer for Microwave product. I very familiar with DFM/DFT and IPC. Besides that i very good in process improvement so that i can capture the possible production before the design release to production.
Below is the project list that I involve :
- Lost cost PIC microchip development board -1 board
- Lost cost Atmel development board - 1 model
- UPS 600 Watt and 1200 watt - 2 model
- Recorder- system - 6 model
- Navigation-system - 50 model(Military/aerospace)
- Microwave oven. - 20 model(Military/aerospace)
- Arduino board - 2 model
- PLC - 1 model
Lets discuss ....
**I currently Altium Designer 10/Proteus VSM/Eagle/Kicad/Orcad 10 user
For PCB assembly process ..
I Certified IPC-A-610 , J-Std-001 and Green belt 6 sigma ...
I very familiar with Oscillosopes,signal generator, power supplies,DVM... and other electronic test tools
Approach to the Job:
Do you need my help to assemble PCB
