1. Single core ARM Cortex-A732 bit core, integrated with NEON and FPU. 2. Equipped with Ruixin Micro's self-developed 4th generation NPU, it has high computational accuracy and supports mixed quantization of int4, in8, and int16. Among them, int8 has a computing power of 0.5 TOPS and int4 has a computing power of up to 1.0 TOPS. 3. Built in self-developed 3rd generation ISP3.2, supports 4 million pixels, and supports various image enhancement and correction algorithms such as HDR, WDR, and multi-level denoising. 4. It has strong encoding performance, supports intelligent encoding, adapts to save bit rates according to the scene, and saves more than 50% of the bit rate compared to conventional CBR mode, making the captured images high-definition, smaller in size, and doubling the storage space. 5. The design with built-in RISC-V MCU supports low-power fast startup, 250ms fast capture, and simultaneous loading of AI model library, enabling facial recognition to be completed within 1 second. 6. The built-in 16 bit DRAM DDR2 can maintain demanding memory bandwidth requirements. 7. Integrated with built-in POR, audio codec, and MAC PHY.
