Ceva-NeuPro-Nano is a fully stand-alone neural processing unit (NPU), not an AI accelerator, and does not require a host CPU or DSP. The IP core includes all processing elements of a self-contained NPU, including code execution and memory management.

Key architectural capabilities:

• Fully programmable architecture for executing neural networks, feature extraction, control code, and DSP code
• Supports advanced ML data types and operators including native transformer computation, sparsity acceleration, and fast quantization
• Efficiently executes a wide range of neural networks with high performance

Two cores are available:

• Ceva-NPN32
• Ceva-NPN64 (includes hardware sparsity acceleration for 2× effective performance)

Additional advantages:

• Hardware-based weight decompression reduces memory footprint by up to 80%
• Full support through Ceva-NeuPro Studio, enabling importing, compiling, and debugging models from frameworks such as LiteRT and µTVM

The Ceva-NeuPro-Nano NPU family is specially designed to bring the power of AI to the Internet of Things (IoT), through efficient deployment of Embedded ML models on low-power, resource-constrained devices. Ceva-NeuPro-Nano NPUs’ optimized, self-sufficient architecture enables them to deliver superior power efficiency, with a smaller silicon footprint, and optimal performance for Embedded ML workloads, compared to the existing processor solutions, which utilize a combination of CPU or DSP with a separate AI accelerator.

The Ceva-NeuPro Studio, which leverages open source AI framework and provides an easy-to-use software development environment, extensive pre-optimized models in the Ceva Model Zoo, and a wide range of runtime libraries, speeds product development for chip designers, OEM’s and software developers.
