RK3568 Security Backend Solution Enables Comprehensive Hardware Upgrade for NVR/XVR
As the video surveillance system evolves towards digitization, networking, high definition, and intelligence, the market demand for network video surveillance systems is increasing. With the extensive involvement of the security industry, especially with the full implementation of projects like Safe Cities and Intelligent Transportation, monitoring scenarios are becoming more complex and dispersed, and the application of backend devices NVR/XVR is gradually expanding, with continuously increasing performance requirements.Recently, Rockchip launched a new security backend NVR/XVR chip solution, the RK3568, which empowers a comprehensive hardware upgrade for NVR/XVR through its four major features.RK3568 NVR Application Block DiagramRK3568 XVR Application Block Diagram1. RK3568 has powerful core processing capabilities, ensuring stability and efficiency in backend data processing
The RK3568 CPU is a quad-core Cortex-A55, utilizing the new Arm v8.2-A architecture, effectively improving performance. It is built with a 22nm advanced process, providing low power consumption and high performance.
The GPU is a Mali-G52 2EE, with a dual-core architecture, supporting image APIs such as OpenGL ES 3.2, 2.0, 1.1, and Vulkan 1.1.
It features Rockchip’s self-developed third-generation NPU RKNN, with a computing power of 0.8 Tops, supporting one-click conversion for mainstream model architectures like Caffe/TensorFlow/TFLite/ONNX/PyTorch/Keras/Darknet.
Powerful encoding and decoding capabilities: supports 4K H.264/H.265 and various formats for high-definition decoding, supports simultaneous decoding of multiple video sources, and can handle up to 10*1080P30 H264/H265, supporting encoding and decoding at the same time; supports 1080@120fps H.264 and H.265 encoding, with support for CBR, VBR, FixQp, AVBR, and QpMap, and supports ROI encoding.
2. RK3568 supports a rich variety of RAM/ROM types, ensuring safety and reliability for data storage
Supports a variety of DDR chip types, including DDR3/DDR3L/DDR4/LP3/LP4/LP4x, with full-link ECC support for DDR3 and DDR4, meeting the requirements of high-reliability products like industrial control, with a 32-bit width and a maximum data rate of 3200 Mbps, providing ample bandwidth to meet the needs of intelligent security NVR/XVR scenarios.
Supports a variety of Flash types, including SPI NOR/SPI NAND Flash/NAND Flash/eMMC, with a dual-ROM coexistence design for SPI Flash+eMMC, meeting the differentiated dual-system design requirements.
Can provide tested and verified DDR core templates and core component selection tables, facilitating rapid productization for customers.
3. RK3568 features excellent power consumption control technology, resulting in lower heat generation and strong environmental adaptability
Rockchip’s self-developed S-Boost power control technology improves performance by 10% at the same voltage and reduces power consumption by 20% at the same frequency. Combined with the energy-saving advantages of the 22nm advanced process, the heat generation of security backend products is more balanced, making them more reliable in high-temperature environments.
Rockchip’s self-developed super standby mode, under the LPDDR4X application scheme, through hardware and software cooperation, can reduce the overall power consumption to 1.6mA (3.8V power supply), suitable for products with special ultra-low power consumption requirements.
4. RK3568 supports rich interface expansion, enabling three-screen display to meet diverse security scenario needs
Features more flexible IOMUX, allowing for multifunctional pin combinations based on product requirements, meeting various functional combination needs.
Supports various video input and output interfaces, with output interfaces supporting built-in touch screen, capable of supporting up to three screens; input interfaces can connect external cameras or expand multi-camera input capabilities. Compared to traditional NVR solutions, RK3568 adds local display output interfaces and camera input interfaces, achieving integrated display, which aids in the application of different types of security backend product forms.
High-speed interface options are rich, supporting 2 RGMII interfaces, supporting PCIE2.1, PCIE3.0, up to 3 SATA3.0, 2 USB2.0, and 2 USB3.0; PCIE interfaces make high-speed throughput applications for 5G and WiFi6 possible, supporting operators and cloud services.
The RK3568 security backend NVR/XVR solution, in addition to traditional access, storage, forwarding, and decoding applications, based on its high-performance AI computing power, can also develop intelligent applications in areas such as facial comparison alarms, intelligent vehicle detection, boundary intrusion warnings, and fire visual warnings, reconstructing edge value.Facial Comparison AlarmThe RK3568 solution can support video stream or image stream detection and recognition, outputting real-time face comparisons by identifying facial attributes such as gender, age, and expression.Intelligent Vehicle DetectionSupports functions such as image-based searches, face-based searches, comparative linkage, second-level retrieval, and alerting.Boundary Intrusion AlarmBased on Rockchip’s self-developed efficient RKNN AI processing unit, the RK3568 solution implements applications for area intrusion and boundary detection, recognizing targets such as humans and vehicles, filtering various environmental interferences like plants, light and shadow, and small animals to avoid false alarms.Fire Visual WarningBased on the powerful core processing capabilities of RK3568, it supports a security NVR system centered around temperature rise detection and smoke detection, capable of marking smoke and fire points, with video linkage for rapid verification, meeting early fire detection needs.Currently, the RK3568 security backend solution has entered mass production. Meanwhile, Rockchip has launched two evaluation development boards based on RK3568, specifically for NVR/XVR scenarios and DDR4 evaluation boards for industrial control security scenarios, aiming to help downstream partners quickly adapt and validate related product functions, facilitating the comprehensive hardware upgrade and product implementation of the new generation of intelligent security backend devices.RK3568 NVR Demo BoardRK3568 DDR4 EVB
