Bitcoin mining computer architectures

The SHA-256 algorithm is a well-defined sequence of steps that consists of simple Boolean operations performed repetitively on 32-bit data items. The algorithm does not require very much memory when operating on a small block (bitcoin block headers are always 80 bytes). This type of problem is ideal for performance optimization using a digital hardware design dedicated to this application.

The input to the mining algorithm is a candidate block header. The bitcoin block header contains the following data items:

Bitcoin version number (4 bytes): This field identifies the version of the bitcoin core software. The miner selects a version number that is compatible with the miner’s bitcoin software.
Previous block hash (32 bytes): The hash of the previous block in the blockchain. This value is retrieved from the bitcoin network as the hash of the current latest block in the blockchain.
Merkle root (32 bytes): This hash...
