Features:
1. Single-core ARM Cortex-A7 32-bit core, integrated NEON and FPU
2. Built-in Rockchip's self-developed fourth-generation NPU, with high calculation accuracy and support for int4, int8, and int16 mixed quantization. The computing power of int8 is 0.5 TOPS, and int4 can reach 1.0 TOPS
3. Built-in self-developed third-generation ISP3.2, supports 4 megapixels, and has various image enhancement and correction algorithms such as HDR, WDR, and multi-level noise reduction.
4. Powerful encoding performance, supports intelligent encoding mode and adaptive throttling according to the scene, saving more than 50% bit rate than conventional CBR mode, making camera images higher-definition, smaller in size, and doubling the storage space
5. The built-in RISC-V MCU supports low power consumption and fast startup, supports 250ms fast image capture and simultaneous loading of the AI model library, achieving "one second" face recognition
6. Built-in 16-bit DRAM DDR2, capable of meeting the required memory bandwidth
7. Integrated built-in POR, audio codec and MAC PHY
