Shift Vector Arithmetic Instructions Implementation to NRV

[shahzaibk23]

To Shift all the RVV Arithmetic Instructions that are successfully done in Vaquita, into NucleusRV.

Goals:

• All previously done instructions in Vaquita working on NRV.
• V should be parametrized like all other extensions in NRV (i.e M,F,C)
• All Compliances for I,M,F and C should not break.
• Vector Verification (RISCOF and/or Random Instructions DV)

Update on Shifting RVV Arithmetic and Configuration Instructions to NucleusRV

I have successfully completed the first two steps of this task and made significant progress in addressing data and structural hazards. I'd like to provide a summary of our my progress and the next steps to be taken.

Completed Steps:

1. All Previously Done Instructions in Vaquita Working on NRV: I have successfully shifted all RVV Arithmetic Instructions from Vaquita to NucleusRV. These instructions are now operational within the NucleusRV framework.

2. Parameterization of V Extension: In alignment with the standard practice for RVV extensions in NucleusRV.
   Next Steps:

3. Compliance Assurance: The parameterization should not compromise compliance with the I, M, F, and C standard specifications. I have thoroughly reviewed the code to ensure that no violations are expected.

4. Data and Structural Hazards Mitigation: I have made significant progress in addressing data and structural hazards but still there are some potential hazards that are needed to be addressed.

5. Vector Verification: In the coming stages, we will conduct comprehensive vector verification, including testing with RISCOF and random instructions to validate the the V extention

Verification Status:

I've manually performed verification using gtk wave. The Next goal is to update the compliance for automated testing.
