Can someone explain to me what is the fcs_ctrl is?

I saw this circuit in this website(http://www.nigamanth.net/vlsi/ ).After I read it, I still don't understand how does the fcs_ctrl value comes from.

Anyone can explain it to me?

Thanks!

There is an explanation of that control signal at the website you cite, but a couple links down:

The FCS_CTRL in this circuit schematic stands for Frame Check Sequence Control. It is a component used in data communication systems to ensure the accuracy of transmitted data. The FCS_CTRL value is generated using a mathematical algorithm and is attached to the data being transmitted. The receiver of the data can then use this value to verify if the data received is the same as the data that was sent. If the values do not match, it indicates that there was an error in the transmission and the data needs to be retransmitted. This helps to ensure the reliability and integrity of the data being transmitted. The specific implementation of the FCS_CTRL in this circuit may vary depending on the specific communication protocol being used.
