SHA-384, SHA-512, SHA-512/224, and SHA-512/256 - 2023.2 English

As SHA-384 and SHA-512/t is simply truncated SHA-512 with different initialization values, they share the same internal structure, as illustrated in the figure above.

A single instance of one of SHA-384/SHA-512/SHA512-224/SHA512-256 processes input message at the rate of 1024 bit / 84 cycles at 313.28MHz/323.31MHz/310.26MHz/313.57MHz.
