About femtoAI
femtoAI, formerly Femtosense, designs the Sparse Processing Unit (SPU), a low-power AI chip for speech, audio and other one-dimensional sensor data in devices such as hearing aids and earbuds. Sparse processing means the chip skips the zero-valued weights and activations in a neural network, which saves memory and energy. The SPU-001 has 1 MB of on-chip memory and is made on a 22 nanometer process, and the company says such workloads can run below one milliwatt. It was founded in 2018 and is based in San Bruno, California.

What femtoAI works on
Edge Computing
Edge computing means processing data close to where it is produced, on a device or a nearby server, instead of sending everything to a distant cloud data center. In chip terms, edge processors are small, low-power chips that run software and AI models inside phones, cameras, cars and sensors.
AI Accelerators
An AI accelerator is a chip, or a part of a chip, designed to run machine learning faster or with less energy than a general-purpose processor. The category includes GPUs, TPUs, neural processing units (NPUs) and chips from many startups.
