XS7320 chip is a digital SOC designed for intelligent IPC (network camera) applications, equipped with high-performance ISP technology and the most advanced H.265 (HEVC), H.264 encoder and JPEG encoder, integrated DDR3/3L/4 (2133Mbps), USB2.0, POR, RTC, Audio Codec modules, rich MIPI, I2C, SPI, GPIO, UART and other interfaces, and output the common peripheral operating clock.
The chip supports high-definition CMOS Sensor input, and can realize triple stream output through ISP processing, video pre-processing and audio/video encoder compression; embedded CPU processor, GPU processor (supporting OpenVX/OpenCL) and CNN hardware acceleration unit can realize mainstream intelligent applications such as face recognition and license plate recognition.
