Rockchip RKnanC chip processor introduction
RKnanC is a low-cost, low-power, high-efficiency digital multimedia chip, which is an ARM-based low-power processor structure and hardware accelerator. It is designed for portable audio product applications, such as MP3 players, etc.
RKnanC can support decoding of various audio standards, such as MP3/WMA/OGG/Mark/AAC, etc. Thanks to the built-in audio hardware accelerator, rknanc can implement audio decoding in very low-end systems. IF, which can save the power consumption of the chip. By providing a complete set of peripheral interfaces, RKnanC can support very flexible applications, including NAND Flash, LCDC, USB OTG, SD/MMC, I2C, I2S, SPI, UART, PWM, etc.
