This repository contains a variety of Digital Signal Processing (DSP) accelerators designed in a configurable and modular fashion. Currently available are listed below:

• sdf-fft - A Single-Path-Delay-Feedback (SDF) Fast Fourier Transform (FFT) hardware accelerators

The following software packages should be installed prior to running this project:

• sbt
• Verilator

To access detailed documentation for each design generator, please refer to the directory doc/name_of_the_generator/ (e.g. doc/sdf-fft) .

This project is intended to be used and run inside chipyard environment. However, if you wish to use this repository independently, please adhere to the instructions below:

• Clone the repository
• Navigate to the directory
• Initialize all necessary tools and submodules
• Compile the code, generate Verilog, or execute tests

git clone https://github.com/ucb-bar/dsp-blocks.git
cd dsp-blocks
./scripts/init_submodules_and_build_sbt.sh
sbt compile

The script init_submodules_and_build_sbt.sh is responsible for setting up all necessary tools and generators essential for running this project. Additionally, it configures build.sbt with accurately defined dependencies, aligning with the chipyard 1.10.1 release. Users have the flexibility to modify versions by adjusting the corresponding checkout commits within the same script.

Conversely, the script remove_submodules.sh executes commands that reverse the actions performed by init_submodules_and_build_sbt.sh.

Please have in mind that modifying the commit may result in potential issues related to tool dependencies.
