HeroSDK is an open-research software development kit for heterogeneous RISC-V platforms. This project enables deploying accelerated Linux user space applications using OpenMP target for programmable multi-core clusters. We currently target Carfield and Occamy.
HeroSDK is a continuity of Hero and HeroV2 but both projects are not yet compatible. Use the original Hero repository for everything referred to HeroV2.
HeroSDK is developed as part of the PULP project, a joint effort between ETH Zurich and the University of Bologna.
The HeroSDK contains compilers (Linux GCC & Bare metal LLVM), Linux kernel modules, host and device runtimes. See the figure felow for more informations.
First, fetch the required repositories:
git submodule update --init --recursiveThis repository contains the following directories:
| Directory | Contains |
|---|---|
apps |
Some example applications using OpenMP |
artifacts |
Automatically managed artifact cache |
cva6-sdk |
The cva6-sdk git submodule containing Buildroot |
docs |
Files used to build the documentation |
install* |
LLVM and compiled binaries and libraries. Also contains device's compiled newlibs. |
output* |
Intermediary compilation folder for LLVM and newlibs. |
platforms* |
The hardware platforms available (cloned on demand) |
scripts |
Helper scripts |
sw |
Hero runtime library, LLVM libraries, the OpenMP target runtime library, and the device drivers |
toolchain |
An LLVM fork containing the Hero OpenMP target runtime library implementation |
| * generated files |
To build the software stack, compile a FPGA bitstream, get a Linux image, and more, go to Getting Started.
This project contains the following dependancies:
- CVA6-sdk to build Linux images using Buildroot.
- llvm-project to build the heterogeneous compiler and OpenMP target runtime.
- o1heap to manage dynamic memory allocation for device.
