The present invention provides a data interaction method and system between a baseband processor and an application processor, including: a baseband processor and an application processor, the baseband processor has an SDC interface, and the application processor has an enhanced dual-port random memory circuit; the baseband processor accesses the enhanced dual-port random access memory circuit through the SDC interface; the application processor accesses the enhanced dual-port random access memory circuit through a system bus. The present invention sets an enhanced dual-port random access memory circuit (Enhanced DPRAM) inside the application processor, which has a dual-port access function, that is, both the baseband processor and the application processor can access the enhanced dual-port random access memory circuit, thereby realizing Data exchange between baseband processor and application processor.
Description
technical field [0001] The invention relates to the technical field of communication, in particular to a data interaction method and system between a baseband processor and an application processor. Background technique [0002] On the mobile communication terminal system, the baseband (MODEM) processor needs to exchange data with the application processor. As the baseband chip supports more and more wireless communication modes, the complexity of its chip structure increases, and the speed of data exchange with the application processor is also required to continue to increase. [0003] In the architecture of mobile communication terminals, the architecture of MODEM processors cooperating with application processor circuits has been widely used. The MODEM processor mainly completes the modulation and demodulation of the baseband signal, and the timing control of the RF transceiver; the application processor mainly completes the control of video peripherals such as display ...
