[0021] The model of ARM 3 is RK3399, and its function is to encrypt the data forwarded by FPGA 2 from wifi module 4, and decrypt the data forwarded by FPGA 2 from CPU 1. ARM 3 is also connected to DDR 7 and eMMc 8 respectively. DDR 7 provides high-speed temporary data storage to support the encryption and decryption operations of ARM 3, while eMMC 8 is used as a non-volatile storage medium, responsible for storing applications and user data, etc., and providing data access during system startup and operation.
