Core-1684XJD4 utilizes the SOPHON AI processor BM1684X, configurable with 16GB of RAM and 128GB eMMC. With computing power of 32TOPS (INT8) peak value, 16TFLOPS (FP16/BF16) computing power, and 2TFLOPS (FP32) high-precision computing power, it supports 32-channel H.265/H.264 1080p@25fps video decoding. It supports mainstream programming frameworks, has a complete toolchain, high usability, and low algorithm migration costs. Suitable for various AI computing scenarios such as visual computing, edge computing, general-purpose computing services, intelligent transportation, unmanned supermarkets, and drones.
The Core-1684XJD4 development board has the HYM8563 RTC (Real Time Clock) chip, which can keep the clock running through the button battery even when the development board is powered off.
The following are common RTC operations:
