Mythic Rises from the Ashes with $125 Million Funding Round 

Excerpt: 

A separate product family, dubbed “Starlight,” will use a Mythic compute chiplet hybrid-bonded under a vision sensor’s photodiode array. The two dies will use less than 1 W between them.
Ozcelik said he noticed a gap in the market for this type of device while previously working at OnSemiconductor.

“One of the biggest challenges for image sensors is low light performance,” he said. “Dynamic range is another major problem, especially in mission critical applications.”

A Mythic AI accelerator could run a neural network to improve low-light performance and dynamic range directly next to the sensor. Image sensors made for applications like cellphones are very small (one-third of an inch), and performance suffers as they get smaller, Ozcelik said. Mythic has a unique opportunity here as its technology is compact, and crucially, it uses very little power, according to Ozcelik (photodiode arrays are extremely thermally sensitive, meaning even a small DSP couldn’t be placed directly under the photodiode array).

Mythic is going to build this sensor and AI accelerator combination itself, and both the accelerator chiplet and the image sensor product will tape out this year, Ozcelik said.

Overall, Ozcelik is pragmatic about the scale of the challenges ahead, particularly given the company’s move into the data center where it will compete with Nvidia.

“[Our advantage] has to be incredibly material,” he said. “It has to be at least one hundred times, hopefully more.”
