Brand-new HSIC interfaces are used to provide high-rate data channels before the AP and the
modem. The interface rate is up to 480 MHz. High-rate serial ports (HSUART) serve as
auxiliary control channels. The memory unit consists of a 32-bit parallel bus, and the storage
unit uses 16-bit parallel ports. External sensors, such as the acceleration sensor, compass, and
gyroscope sensor, are connected to the system through I2C interfaces.
