Test-proven DDR core templates and core device selection tables can be provided to facilitate rapid productization for customers
3. RK3568 has excellent energy consumption control technology, less heat generation, and environmental adaptability
Rockchip self-developed S-Boost power control technology, compared with traditional technology, the performance is improved by 10% under the same voltage, and the power consumption is reduced by 20% under the same frequency. Combined with the energy consumption advantages of 22nm advanced technology, the heat generation of security back-end products is more balanced, and the work is more reliable in high temperature environment
Rockchip self-developed super standby mode, under the LPDDR4X application scheme, through the cooperation of software and hardware, the power consumption of the whole machine can be reduced to 1.6mA (3.8V power supply), which can be suitable for products with special requirements for ultra-low power consumption
4. RK3568 supports rich interface expansion, supports three-screen different display, and meets the needs of diversified security scenarios
Has a more flexible IOMUX, pin multi-function combination application, can be selected according to product requirements, to meet more diverse functional combination requirements
It supports a variety of video input and output interfaces, the output interface supports its own point screen, and can support up to three different displays; the input interface can be used to connect an external camera or to expand the input capability of multiple cameras. Compared with the traditional NVR/XVR solution, RK3568 adds a local display output interface and a camera input interface to realize the integration of display, which is conducive to the application of different types of security back-end products.
The high-speed interface is rich in optional types, supports 2 RGMII interfaces, supports PCIE2.1, PCIE3.0, supports up to 3 SATA3.0, 2 USB2.0, 2 USB3.0; PCIE interface makes 5G and WiFi6 high Speed throughput application becomes possible, realizing support for operators and cloud services and other services
RK3568 security back-end NVR/XVR solution, in addition to traditional access, storage, forwarding, decoding applications, based on its high-performance AI computing power, can also be used in face comparison alarm, intelligent human and vehicle retrieval, cross-border warning, Intelligent application of fire alarm visualization and early warning to reconstruct edge value.
Face comparison alarm
The RK3568 solution can support video stream or image stream detection and recognition, and output face real-time comparison by identifying features such as gender, age, and expression.
Intelligent human vehicle retrieval
Supports functions such as image search by image, face search by face, comparison linkage, second-level retrieval, and alarm control.
The RK3568 solution is based on the self-developed high-efficiency RKNN AI processing unit, which realizes applications such as regional intrusion and cross-border detection. It can identify human/motor vehicles and filter various environmental disturbances, such as plants, light and shadow, small animals and other non-human bodies or vehicles. false positives.
fire alarm visualization
Based on the powerful core processing capability of RK3568, it supports the security NVR system with temperature rise detection and smoke detection as the core. It can mark the orientation of smoke, fire point, etc., and quickly check the video linkage to meet the needs of early fire detection.
At present, the security back-end solution RK3568 has entered the mass production stage. At the same time, Rockchip launched two evaluation development boards based on RK3568, one for NVR/XVR scenarios and one for DDR4 for industrial control security scenarios, aiming to allow downstream partners to adapt and verify related product functions more quickly , to help the comprehensive hardware upgrade and product implementation of the new generation of intelligent security back-end equipment.
