Hash_sha224
===========

Function description:
---------------------

This demo shows the operation of **HASH SHA224**, the means about filling data writed to fifo is *via soft*.

* Configure the **HASH**.
* Enable HASH and filling data by soft to start calculation, **by reading the hash calculation finish status** to judge whether calculation is done.
* Waiting calculation done to compare the result with the golden data to check. 

.. note::
    The golden data getted by hash online calculator.
