RISC-V Vector Examples For Nuclei SDK

These RISC-V Vector Examples are modified based on https://github.com/riscv-non-isa/rvv-intrinsic-doc/tree/main/examples to make it works for Nuclei SDK evalsoc.

Run in command line

You need to download Nuclei SDK >= 0.5.0 version.

• CASE: default branch, which is used to specify which rvv_${CASE}.c you want to run, if set to sgemm, it means rvv_sgemm.c case.

cd /path/to/nuclei-sdk
cd nuclei-board-labs/evalsoc/rvv_examples
# build it
# Assume environment is already setup, see https://doc.nucleisys.com/nuclei_sdk/quickstart.html
# Require Nuclei Studio 2023.10
make all
# run on qemu
make run_qemu
# run on hw
# require NX900FD with vector enabled bitstream
make upload

Run in Nuclei Studio

Nuclei Studio >= 2023.10 is required

You can download this NPK package from Nuclei Package Management or download this source code as zip, and import it.

During the New Nuclei RISC-V C/C++ Project project wizard, select Nuclei FPGA Evaluation SoC, and select sdk-nuclei_sdk @0.5.0

and then select RISC-V Vector Examples example, and choose one case in the choice Vector Case, and then create an example.

Then you can build it and run it in IDE.
