IP Cores
Hardware Accelerator for Crypto currencies
As we go deeper into cryptocurrency and mining, the mining hardware efficiency is the key to success
The mining is becoming increasingly challenging and competitive and the real ROI comes from faster and efficient
hashing
This is possible through custom made designs and modifications in algorithm
We have a very good design that can compete with existing world leaders in bitcoin and litecoin mining
The designs are widely used in security algorithms apart from crypto-currencies, especially SHA256 algorithm (backbone of bitcoin)
