understanding Branch Prediction

[KinzaQamar]

Greetings!!
I am currently understanding the branch prediction mechanism of SweRV El2 and I am captured by alot of confusions. It would be appreciated if I get to know about the following questions:
1- Overveiw of branch prediction implemented in El2
2- Why we are using hashing and folding for Ghr's and PC
3- Why there are multiple GHR's
4- How many are the algorithms involved in this module and what are those ?
5- Implementation of BHT
6- Any example you can give to explain the whole mechansim in steps
7- LRU
