The K210 includes two 64-bit RISC-V CPU cores, each with a built-in independent FPU. The primary functions of the K210 are machine vision and hearing, which includes the KPU for computing convolutional neural networks and an APU for processing microphone array inputs. The K210 features a Fast Fourier Transform (FFT) Accelerator for high performance complex FFT calculations. As a result, for most machine learning algorithms, the K210 has high-performance processing power. The K210 embeds AES and SHA256 algorithm accelerators to provide users with basic security features. The K210 features high-performance, low-power SRAM and powerful DMA for superior data throughput. K210 has a wide range of peripheral units: DVP, JTAG, OTP, FPIOA, GPIO, UART, SPI, RTC, I²S, I²C, WDT, Timer and PWM, for a large number of application scenarios.
