NIR: A Unified Instruction Set for Brain-Inspired Computing

We show how to use the Neuromorphic Intermediate Representation to migrate your spiking model onto neuromorphic hardware.

Have you wondered how to use neuromorphic hardware platforms?

Are you depressed by your power bill after you bought your >400W GPU rig?

Then you came to the right place!

In this workshop, we will show you how to move models from your favourite framework directly to neuromorphic hardware with 1-2 lines of code! We will present the technology behind, the Neuromorphic Intermediate Representation , and demonstrate how we can use it to run a live spiking convnet on the Speck chip.

NIR is currently supported by Intel Loihi , Speck , SpiNNaker2 , Xylo and a host of simulators, including Norse , snnTorch , and Spyx .

Join us on the 5th of February to get your own hands-on experience with NIR and neuromorphic hardware!

All it requires is a computer and a bit of Python knowledge.


  • 18:00 - 19:00: NIR introduction
    • Motivation: coupling neuromorphic hardware and software
    • Demonstrating NIR: from PyTorch to Speck
    • Q&A
  • 19:00 - 20:00: Workshop
    • Hands-on experience with NIR via Jupyter Notebooks or custom models
    • Q&A and collaborative discussions
