Eclipse Webmaster requested to merge github/fork/zetalog/cv32e-novic into master Apr 08, 2020

Created by: zetalog

This patch adds a non-vectorized IRQ mode. When it is configured, CPU fetches the same entry of MTVEC as exceptions upon IRQ arrivals. This allows us to try non-vectorized IRQ based software without the need to modify it.

Tested in a VCS simulation environment.
