Talks and Tutorials

During ARC2019, we gave a tutorial on TaPaSCo, introducing the most important concepts as well as the design flow for composing and interfacing with an FPGA-based accelerator SoC.

The slides are available for download.

We also recorded the whole tutorial, a playlist with videos on the different steps of the TaPaSCo design flow and the setup of TaPaSCo itself is available on our Youtube channel.

We used the Docker image sommerlukas/tapasco-tutorial:arc2019 for the tasks, it's still available for download on Dockerhub.

Arrayinit example (Bitstream + runtime)

Here, we provide the commands for creating a bitstream of the arrayinit HLS core for the Alveo U280. After bitstream creation, we build the runtime example application.

Requirements: Rocky Linux 8, vivado and vitis_hls on the path, FPGA inserted and cable driver installed.
