Ambarella Introduces CV28M SoC With CVflow to Enable New Categories of Intelligent Sensing Devices - Seite 2

The CV28M delivers efficient video encoding in both AVC and HEVC formats. A high-performance image signal processor (ISP) delivers outstanding imaging in low light conditions, and high dynamic range (HDR) processing extracts maximum image detail in high-contrast scenes. CV28M includes a full suite of advanced cybersecurity features to protect against hacking including secure boot, TrustZone, and I/O virtualization. Fabricated in 10 nm ultralow-power process technology, the CV28M chip is optimized for wire-free camera applications that require long battery life and small form factors.

The CV28M chip shares a common SDK and computer vision (CV) tools with Ambarella’s CV25, CV22, and CV2 CVflow SoC families, simplifying development of cameras with multiple price and performance options. A complete set of CV tools helps customers port their own neural networks onto CV28M and includes a compiler, debugger, and support for industry-standard machine learning frameworks such as Caffe and TensorFlow, with extensive guidelines for convolutional neural network (CNN) performance optimizations.

Samples of CV28M are available now.
