Inter-algorithm data transmission method and device in system

The invention discloses an inter-algorithm data transmission method and device in a system. The method comprises the steps of obtaining output data of a first algorithm and storing the output data into a shared memory, wherein the output data comprises a data item of at least one variable; acquiring memory storage structure description information of the output data; determining an initial address of a variable required by a second algorithm according to the memory storage structure description information; and reading the data item of the required variable from the shared memory according to the initial address of the required variable and taking the data item as the input of the second algorithm. According to the method, the data is read through memory storage structure description, the method is irrelevant to specific memory storage structure definition, the problem of data transmission relevance between algorithms can be decoupled, and meanwhile the problems of transmission compatibility and stability cau
