Attending: Nicolò, Stelios, Noemi, Sioni, Maurizio (Zoom)

• Currently 1 order of magnitude smaller than target on parameters size, 2 orders of magnitude better than target on pixels / W / s
• Currently resource limited by LUTs
  • Stelios to look at main consumer of LUTs
• Can latency matching be automated?
• Vladimir’s fellow will work on layer IP stitching
  • Not yet shareable - keep an eye on it
• Pruning from Vladimir’s NGT group
  • Trying 4 different pruning methods
  • Nicolò to follow meeting
  • Potential to feedback to Agenium on methods
• Maurizio to provide EPFL paper on structured pruning
• Propose to look at intermediate layers KD
• Proposals for next steps:
• Study dataflow in more detail
  • Where are bottlenecks?
• Small reusable blocks?
  • Need some reconfigurability in layer code (e.g. non constant image dimensions)
  • Save resources at the cost of throughput
• Different clock frequencies for different layers
  • Yes it’s possible, but needs split layer IPs
• Partial reconfiguration
  • Look into how fast that is
• Nicolò to deliver the CI / reproducibility pipeline
• Short term plan:
  • look into some of the ideas in sandbox environment
  • meet again in two weeks
  • bring material (slides, diagrams, anything)
    • ideally aim to quantify the potential of each idea
    • how much will it realistically impact the resources, latency, throughput etc?
    • how feasible is the implementation?
•
