Patent ID: 7228454

Claim:
A method of processing data according to data type, the method performed by a slave processor and a main processor, wherein the slave processor stores and/or reads transmission data that is either type 1 data that has to be processed in real-time or type 2 data that does not have to be processed in real-time, and the main processor is connected to the slave processor to process at least one among the type 1 data and the type 2 data, the data processing method comprising: the main processor: transmitting at least one reference address to the slave processor; storing the reference address to the slave processor; analyzing whether transmission data to be communicated to the slave processor is the type 1 data or the type 2 data; setting a relative address according to the analyzed result; and transmitting the relative address to the slave processor, wherein the relative address is an address of the slave processor in which the transmission data to be transmitted to the slave processor is to be stored, or an address of the slave processor in which the transmission data to be received from the slave processor is stored; and the slave processor: storing the transmitted reference address; determining whether the transmission data is the type 1 data or the type 2 data by comparing the relative address with the reference address; and correcting errors generated when the transmission data is processed, using predetermined processes according to the determined data type.
