How to change Pulp clusters' core to cv32e40p core

[DongYu2013]

Recently, when I transplanted cv32e40p on the cluster side of Pulp, I have some difficulties——I failed to change the core, but I could not solved it. In addition to the interface mismatch, some internal logic is also different, including the fetching and decoding stages.
In this regard, I would like to ask how to implement Pulp's cluster kernel to cv32e40p. I have read cv32e40p user manual，but I still not success for it.
Thank you.
