Pioneering Analog Compute for
Edge AI to Overcome the End of
Digital Scaling
Mike Henry – CEO/Founder
Mythic
May 2019
© 2019 Mythic, Inc.
The Trends are Clear:
• Insatiable demand for DNN compute
at the edge will only increase
• Models like ResNet-50 are considered
“toys” in production systems
• Developers need Bigger models that
handle more edge cases
• Applications run many concurrent
models with tough latency requirements

aggregation
High value edge
▪ AI applications shifting in
large scale to DNNs
▪ Offers compute density
unlike anything on the market
▪ Targets for Mythic
– On-premise aggregation
– Cloud edge/ datacenter
– High-value edge
▪ Roadmap envisions mobile,
consumer versions

Mythic IPU – Analog DNN Inference Co-processor
Host
PCIe
▪ Co-processor on the PCIe bus
▪ Weights stored in on-chip flash
(INT8)
▪ Compute with analog technology
▪ 19x19mm BGA package
▪ Multiple chips can be tiled on a
single PCIe card or in a system

Mythic’s analog compute lets us deliver what no else can
• Large, powerful models entirely on chip and instantly computable
• Unmatched performance and power efficiency for a given
solution cost
• Rich product roadmap that will far surpass all-digital approaches
as Moore’s Law and DRAM bottlenecks tighten
• Powerful SDK that makes quantization and compilation easy

Conclusions
• Insatiable demand for DNN edge compute will only grow:
• Bigger models
• Huge memory requirements
• Ultra-low latency
• Mythic’s analog compute is the offramp from the End of Moore’s Law
• Keep a close eye on us this year!
