Innovations in Neuromorphic Computing: The Launch of a New Microcontroller Innatera T1

Category articles

The field of neuromorphic computing has taken a significant leap forward with the introduction of a neuromorphic microcontroller by Innatera, a startup specializing in spiking neural network (SNN) accelerators. This development represents a pivotal moment in the application of brain-inspired computing technologies for always-on sensing tasks in consumer electronics and the Internet of Things (IoT).

Revolutionizing Sensory Processing with SNN Technology

Innatera’s neuromorphic microcontroller leverages spiking neural network technology, which mimics the brain’s method of processing information through the emission of precisely timed voltage spikes. This approach facilitates native time series processing, exhibiting superior correlation detection capabilities. Remarkably, SNNs achieve this performance while being approximately 100 times smaller than traditional neural network models, offering a blend of efficiency and compactness that is highly advantageous for sensory processing applications.

Performance Breakthroughs in Neuromorphic Computing

According to assessments, the technology underpinning Innatera’s neuromorphic microcontroller has undergone rigorous validation across five generations of test chips, demonstrating a remarkable 100-fold increase in speed and a 500-fold reduction in energy consumption per inference when compared to conventional neural network implementations. This efficiency leap marks a significant achievement in the optimization of neural networks for digital AI accelerators, including microcontrollers and digital signal processors.

Introducing the T1 System-on-Chip (SoC)

The T1 SoC is Innatera’s latest offering, integrating a small CPU, memory, and a convolutional neural network (CNN) accelerator alongside the company’s proprietary analog SNN accelerator. This integration signifies a comprehensive solution for sensor data analysis, enabling real-time pattern detection and identification within stringent power and latency constraints. The inclusion of a small CPU, specifically a RISC-V design, alongside standard sensor interfaces, allows for seamless sensor data management and processing, further enhancing the microcontroller’s utility in consumer and IoT devices.

Advancements in Analog/Mixed-Signal SNN Acceleration

Innatera’s SNN accelerator, characterized by its analog/mixed-signal computation, enables the programming of various SNNs and their complex neural connection topologies directly onto the chip. This capability, reminiscent of an analog FPGA, allows for a programmable network of neurons and synapses capable of implementing diverse neural network topologies with unprecedented energy efficiency.

Enhancing Flexibility with Dual Accelerator Design

To cater to applications requiring both high performance and low power consumption, Innatera has incorporated a digital accelerator for conventional CNNs alongside its SNN accelerator. This dual-accelerator approach allows the T1 to process spatial, temporal, and spatio-temporal data, making it uniquely suited for a wide range of sensing applications, from person presence detection using radar to sophisticated audio scene classification.

Facilitating SNN Development with Talamo

Innatera supports SNN development through Talamo, a software stack with a Pytorch front-end that integrates custom extensions for SNNs. This infrastructure streamlines the development and training of SNNs within the familiar Pytorch framework, making advanced neural network design accessible to a broad range of developers.

The Path Forward for Innatera

With backing from the European Innovation Council and private investors, Innatera has rapidly expanded its team and is poised to scale production of the T1 microcontroller. The company’s advancements in neuromorphic computing not only showcase the potential of SNNs in real-world applications but also herald a new era of efficient, intelligent sensing solutions for the technology sector.
