RapidIO-based high-speed communication method

The invention relates to the technical field of embedded system application, in particular to a RapidIO-based high-speed communication method, which comprises the following steps of: when a hardware link connection state is normal, initializing RapidIO peripheral configuration, and receiving and/or sending data through RapidIO; the step of sending the data comprises the substeps of querying a data chain table to obtain an available data cache region, converting a base address of the data cache region and a data sending destination address, sending the data to the data sending destination address, and sending a doorbell; the step of receiving the data comprises the substeps that after the current node receives the doorbell, a data chain table is inquired to obtain an available data cache region, a base address of the data cache region is converted, and the received data is copied. According to the method, a linked list mechanism is introduced on the basis of RapidIO, the requirement for high reliability of Rap
