VAQUITA - RISC-V Vector Core

Introduction:

"Vaquita" 🐬, named after the critically endangered Vaquita porpoise, represents a groundbreaking project at the intersection of technology, education, and environmental consciousness. It introduces the RISC-V vector extension, an enhancement to the RISC-V instruction set architecture that introduces powerful support for vector operations. This extension includes vector registers and a comprehensive suite of vector instructions, enabling efficient parallel processing of large datasets.

Getting Started

To begin working with Vaquita and exploring the RISC-V vector extension, follow these steps:

1. Clone this repository to your local machine:

   git clone https://github.com/your-username/vaquita.git
   

2. Navigate to the project directory:

   cd vaquita
   

3. Edit the path to the input text file in the test configuration. Open src/main/scala/rvv/RISC5.scala and replace /home/yourname/vaquita/vector_input.txt with the path to your local machine's input text file.

4. Build the project using SBT (Scala Build Tool):

   sbt
   

5. Once you're in the SBT interactive shell, you can run the test suite with VCD (Value Change Dump) output enabled. To run the tests for the RISC-V vector processor with VCD output, use the following command:

   testOnly rvv.RISC5Test -- -DwriteVcd=1 

This command will execute the test suite for the RISC-V vector processor and generate VCD files for debugging and analysis.

7. The test case being run is as follows:

   vsetvli x1, x2, e16, m1, vma
   lui x1, 0xa
   srli x2, x1, 12
   vmv.v.v v0, v1, x2
   vadd.vi v3, v7, 3, vm=0
   

8. The expected output on register v3 will be

This output represents the result of the vadd.vi operation where each element of vector v3 is incremented by 3.
