At the same time, after the data stream is frame encoded by the first read-write control module, the framing code data can be synchronized to the second read-write control module through the transmission control module, so that the second read-write control module can effectively perform encoding and decoding processing when reading the data, thereby reading the data stream.

[0031] In the embodiment of the present application, since the first read-write control module and the second read-write control module both perform flow control according to the same transmission control module, when writing and reading data, data overflow when the dual cores simultaneously write data can be effectively avoided, the utilization rate of the storage space is improved, and the transmission bandwidth is increased.

[0045] In an alternative embodiment, Figure 3The schematic diagram of the dual-core communication processor structure provided in the embodiment of the present application, the first processor and the second processor are CORE_0 and CORE_1 respectively, taking the transmission from CORE_0 to CORE_1 as an example, if there is free space in the shared storage module, the data stream sent by CORE_0 will enter the frame coding_0 module through the flow control module. The frame coding_0 module will compile the data stream into several data frames according to the continuity of the data stream, the maximum frame length, the available space of the shared storage, and other information, and add the frame header, frame length, CRC check, frame tail, and other information, and output the data frame to the write control_0 module.
