Ariane CVA6 - an Application class 6-stage 64-bit RISC-V CPU capable of booting Linux.

CVA6 fully implements I, M, A and C extensions as specified in Volume I: User-Level ISA V 2.3 as well as the draft privilege extension 1.10. It implements three privilege levels M, S, U to fully support a Unix-like operating system. Furthermore it is compliant to the draft external debug spec 0.13.

It has configurable size, separate TLBs, a hardware PTW and branch-prediction (branch target buffer and branch history table). The primary design goal was on reducing critical path length.
