Message exchange method and interface processing platform

The invention relates to the technical field of wireless communication, in particular to a message exchange method and an interface processing platform, and aims to solve the problem that a current MAC-PHY (medium access control-physical layer) interface processing platform is complex in processing message exchange process. The message exchange method includes the steps: reading a message packet in a shared memory shared by a DSP (digital signal processor) core and an upper layer by the DSP core positioned at an upper level of the interface processing platform; storing the message packet in a local memory of the DSP; determining a DSP core positioned at a next level and needing to process messages; storing the messages in a shared memory shared by the messages and the DSP core positioned at the next level in the form of the message packet. By the aid of the technical scheme, message exchange between an MAC layer and a PHY layer is realized by the shared memory, and processes such as parameter configuration in message sending at a current interface are avoided, so that complexity of the processing message exchange process of the MAC-PHY interface processing platform is reduced.
