Abstract
In a data processing device comprising a memory controller controlling writing/reading of data to/from the memory, a processor requesting writing/reading of data, and an error detection module requesting writing/reading of data to/from the memory controller in accordance with a request from the processor, an error detection module calculates a first error detection code of the first data having a write request from the processor, reads the second data having a read request from the processor from the memory, calculates a second error detection code from the read data, compares the first error detection code and the second error detection code, and transmits the result of the comparison to the external module.
