CDNN is a comprehensive toolkit that simplifies the development and deployment of deep learning systems for mass-market embedded devices. Tailored and optimized for the CEVA-XM family of imaging and vision DSPs, the CDNN toolkit includes the CEVA network generator, the CDNN software framework and a CNN hardware accelerator that works in tandem to deliver superior performance while ensuring flexibility with the constantly evolving requirements of machine learning.

Separately, each component of the CDNN toolkit is a powerful enabler of embedded imaging & vision applications. Combined, these pieces deliver an ultimate toolkit to support new network structures and changing layer types of deep neural networks.

CEVA supplies a full development platform for partners and developers based on the CEVA-XM family of DSP cores to enable the development of deep learning applications using the CDNN, targeting any advanced network.


The CDNN toolkit streamlines implementations of deep learning in embedded systems by automatically converting offline pre-trained neural networks to real-time embedded-ready networks for CEVA-XM cores, utilizing the CEVA Network Generator. This enables real-time high quality image classification, object recognition and vision analytics.
