Ambarella Expands Security AI Vision SoC Portfolio

AmbarellaCV5S 400x275

June 21, 2021

Ambarella, which develops AI vision technologies, has announced the expansion of its AI vision system-on-chip (SoC) portfolio with the new CV5S and CV52S security families. Based on the company’s CVflow architecture and 5nm process technology, the new SoCs support simultaneous 4K encoding and advanced AI processing in a single low-power design, and is aimed at security camera applications that require multiple sensors for 360-degree coverage over a wide area and with long range, such as outdoor city environments or large buildings.

The CV52S family is designed for single-sensor security cameras with advanced AI performance that need to more clearly identify individuals or objects in a scene, including faces and license plate numbers over long distances, such as traffic cameras.

“Security system designers desire higher resolutions, increasing channel counts, and even faster and more ubiquitous AI capabilities,” said John Lorenz, senior technology and market analyst at Yole Development. “Ambarella’s newest AI vision SoCs for security are competitive solutions for meeting the growing demands of the security IC sector, which we forecast to exceed $4 billion by 2025, with two-thirds of that being chips with AI capabilities.”

The CV5S SoC family supports multi-imager camera designs, and can simultaneously process and encode four imager channels of up to 8 megapixel, or 4K resolution, each at 30 frames per second while performing advanced AI on each 4K imager, Ambarella said. The SoCs are able to double the encoding resolution and memory bandwidth while consuming 30% less power than the company’s prior generation, Amarella added. The CV52S family supports 4K resolution at 60fps, while providing four times the AI computer vision performance, two times the CPU performance and 50% more memory bandwidth than its predecessors. Increased neural network performance enables more AI processing at the edge, instead of in the cloud, the company said.

“The global security industry is rapidly moving to higher 4K resolutions while increasing AI algorithm capabilities, to achieve better recognition of people and objects, along with multiple imagers for a wider field of view and longer range,” said Jerome Gigot, senior director of marketing at Ambarella. “Our new CV5S and CV52S security AI vision SoC families respectively support 4K multi-imager or high-frame-rate 4K single-imager designs with high performance edge AI processing, allowing the development of cameras that do not need to compromise between image resolution and AI processing accuracy.”

In addition to security applications, the company said there are other IoT-related applications that can benefit from the high resolution and advanced AI processing. This includes smart city applications such as traffic management, accident detection, and automated speed control, as well as the rapid location of missing or stolen vehicles. Smart retail operations can use the resolution to better manage product placement, adjust cashier staffing for real-time line management, enhance warehouse product tracking, and provide more intelligence at the store and corporate levels.

Ambaralla said additional features of the CV5S and CV52S include:

  • SDK created specifically for the security camera market
  • CVflow tools that are compatible across all security families
  • Dual Arm A76 1.6GHz CPUs with 1MB of L3 memory; a 2x performance gain over the prior generation for faster customer applications
  • Enhanced ISP with HDR, ISO low-light, dewarping and rotation performance
  • On-chip privacy masking to block out a portion of the captured scene
  • New PCIe and USB 3.2 interfaces, enabling more complex, multi-chip security system designs than prior generation
  • On-chip cybersecurity hardware to ensure secure IP cameras, including secure boot, OTP and Arm TrustZone technology
  • Multiple video inputs, with support for up to 14 cameras using MIPI virtual channels
  • SLVS-EC interface on the CV5S for reduced system design complexity
  • Support for LPDDR4x, LPDDR5 and LPDDR5x DRAM

Samples of the CV5S and CV52S SoC families are expected in October. For more details, visit the Ambarella website.
