Overview

This tutorial offers step-by-step guidance covering the process from spike-based learning to FPGA prototyping.

Prerequisites

• https://github.com/rvx-etri/npx-xarvis.git

• https://github.com/rvx-etri/npx-tutorials.git

• NPX Tutorial - Xarvis

• RVX Tutorial - Hello

• An RTL simulator with mixed-language support

• A Genesys2 FPGA board connected to your computer - Manual

Things to Know

• Any part starting with # should be replaced or modified according to your environment.

• On Linux, use the bash shell for command-line operations.

• On Windows, use the Windows Power Shell for command-line operations.

Installing the Xarvis and RVX Environment

Follow the two tutorials in the Prerequisites to install both the Xarvis and RVX.
The directories cloned from npx-xarvis.git and npx-tutorials.git are called ${XARVIS_HOME} and #(tutorial dir), respectively.
In this tutorial, we’ll use #(tutorial dir)/platform/starc_neugemm as the platform directory, referred to as #(platform dir).

Synchronizing with Xarvis

cmd) source #(tutorial dir)/rvx_setup.sh
cmd) source ${XARVIS_HOME}/rvx_setup.sh
cmd) cd #(platform dir)/util/npx
cmd) make setup

Synthesizing the Processor

cmd) cd #(platform dir)
cmd) make syn

Training an Example Application

cmd) cd #(platform dir)/util/npx
cmd) make mnist_app

Running an NPX Application via RTL Simulation

Not recommended because it takes a long time.

cmd) source #(tutorial dir)/rvx_setup.sh
cmd) cd #(platform dir)
cmd) make sim_rtl
cmd) cd sim_rtl
cmd) make test_npx_app.all

Prototyping the Processor on the Genesys2 Board

cmd) source #(tutorial dir)/rvx_setup.sh
cmd) cd #(platform dir)
cmd) make genesys2 // replace with your board name
cmd) cd imp_genesys2_YYYY-MM-DD // referred to as #(fpga dir)
cmd) make imp

Running an NPX Application on the Genesys2 Board

cmd) source #(tutorial dir)/rvx_setup.sh
cmd) cd #(fpga dir)
cmd) make program
cmd) make printf
cmd) make test_npx_app.all
