US Patent 7558285 Data processing system and data interfacing method thereof

A data processing system includes a data processing module and a data interface module. The data processing module may perform a data processing function and interface with other data processing systems using data packets having a first protocol format including actual data and control data. The data interface module may convert data packets having the first protocol format to data packets having a second protocol format, may output the data packets having the second protocol format to the data bus, may convert data packets having the second protocol format to data packets having the first protocol format, and may transfer the data packets having the first protocol format to the data processing module. The data processing system may be capable of processing both standardized actual data and control data for transferring the standardized actual data, and capable of simultaneously supporting an asynchronous interface and a synchronous interface.
