Embodiment Construction
[0024] At first, explain the core of the present invention: adopt three-port random access memory RAM as the data communication medium between AP application processor and two wireless communication subsystems, realize the data transmission when dual-mode dual-standby, on software and hardware Adopt a set of corresponding arbitration mechanism and timing and divide the data space of the three-port RAM, so as to ensure the reliability and correctness of the communication between the AP and the two wireless communication subsystems.
[0025] (1) System Architecture
[0026] The system architecture of the 3G dual-mode intelligent mobile terminal is divided into several modules, namely: AP application processor module, the first wireless communication subsystem (3G wireless communication subsystem), the second wireless communication subsystem (GSM, EDGE, CDMA or other standard 3G wireless communication subsystems), peripheral function modules and input and output modules, etc. Am...
