PowerVR Series2NX

NEURAL NETWORK ACCELERATOR

The highest performance neural network inference accelerator

The PowerVR Series2NX is a complete neural network accelerator (NNA) solution for AI chips or functionalities used in embedded and mobile devices. Designed to deliver high-performance computation of neural networks at very low power consumption it performs over 4.1 Tera Operations Per Second (TOPS), making it the highest performance density per mm2 in the market.

Neural network acceleration for edge devices

As neural networks drive an explosion in technological progress across industries, NNAs are now a fundamental class of processor, as significant as CPUs and GPUs.  By integrating a PowerVR Series2NX Neural Network Accelerator (NNA) manufacturers can build devices that offer high-performance computation of neural networks at very low power consumption, in minimal silicon area. Offering this processing in edge devices, removes the limitations of the cloud, such as bandwidth constraints, latency issues and privacy concerns.

Designed from the ground-up for artificial intelligence

The PowerVR Series2NX represents an entirely new type of architecture, designed from the ground-up to provide hardware acceleration for the next generation of artificial intelligence within embedded platforms. Delivering up to 4.1 Tera Operations Per Second (TOPS), the Series2NX offers the highest inference/mm2 available on the market, enabling the creation of compact and cost-effective inferencing solutions.

Scalable architecture for multiple markets

PowerVR Series2NX is designed with scalability in mind, licensable in IP cores that hit different performance points and feature sets to address multiple markets and applications.

Flexible bit-depth data type support

As a fully flexible solution, the Series2NX supports neural network bit depths from 16 down to 4-bit, reducing bandwidth and increasing performance without compromising inference accuracy.

Leading performance with low power consumption

With the industry’s highest inference/mW, the Series2NX delivers class-leading neural network acceleration with the lowest power consumption.

Putting the smart in smartphone

In mobile devices where a GPU is mandated, device manufacturers can pair a new PowerVR Series9XE or 9XM GPU with the Series2NX NNA in the same silicon footprint as a competing standalone GPU. Machine learning is now deployed in a wide variety of mobile applications, such as face recognition and verification, object recognition, image enhancement, style transfer and music tagging to name but a few. To support this, our Series 2NX NNA cores deliver a paradigm shift in performance, while simultaneously reducing battery consumption over pure GPU solutions.

Automotive (ADAS)

Convolutional neural networks (CNNs) are playing a crucial role in developing self-driving cars. The Series2NX NNAs will power advanced driver-assistance systems (ADAS) including driver alertness monitoring, driver gaze tracking, seat occupancy, road-sign detection, drivable path analysis, road user detection and driver recognition.

augmented-reality

Augmented & Virtual reality

Neural network hardware acceleration will be critical to fulfil the potential of next-gen augmented and virtual reality use cases. Scene understanding will enhance augmented reality, while movement analysis, eye tracking and gesture recognition will provide context awareness in virtual reality to provide the best possible relative user experiences.
