Abstract A data processing system is composed of microprocessor, memory and special application chip whose work frequency is higher than that of microprocessor. Its data access method includes such steps as generating initiation control signals and the first address signal by microprocesor, respectively reading the first address signal and the first data from memory by said chip, converting the first data to the second data, returning it back to microprocessor, transmitting the third data to said chip by microprocessor, converting the third data to the fourth data by said chip, and storing the fourth data to memory according to the second address signal.
