AutoDNNchip

This is a Python implementation of the conference paper AutoDNNchip: An Automated DNN Chip Predictor and Builder for Both FPGAs and ASICs at FPGA'20.

Chip Predictor requirement: Python 3.6 (conda environment based on conda_env.yml).

AutoDNNchip Generated FPGA design requirement: Xilinx Ultra96 FPGA.

Preparation

Add your hardware library to ./hw_libs.

Generate a graph definition based on templates or from scratch

Change the hardware configuration files ./template_config and generate a graph based on graph templates. An example:

$ python main_def_graph_from_template.py --template systolic2x --template_config template_config/systolic2x_3.js --store graph_defs/systolic2x_3x3.graph

Or build a graph definition from scratch. An example:

$ python main_def_graph_from_scratch.py --store graph_defs/conv_eg.graph

Run the cycle by cycle simulation of Chip Predictor based on graph definition

$ python main_sim_from_graph.py --graph_def graph_def_file | tee log_file

An example:

$ python main_sim_from_graph.py --graph_def graph_defs/conv_eg.graph | tee logs/conv_eg.log

Run the optimized design on Ultra96 FPGA

We compare our optimized FPGA design with the champaign-winning design in the 56th IEEE/ACM Design Automation Conference System Design Contest (DAC-SDC). To run the baseline design and our optimized design, first download the sampled test images, copy the ./optimized_ultra96 to your FPGA, then run:

$ sudo python3 main.py --option optimized

and

$ sudo python3 main.py --option baseline
