US Patent 11190805 Data processing device and data processing method

Provided is a data processing device that reduces the amount of memory access in a case where data and an error control code are to be stored in a memory. The processing device includes a data compression section, a code generation section, a binding section, and a transfer section. The data compression section generates second data by performing a predetermined compression process on first data that is to be stored in a memory and of a predetermined data length. The code generation section generates an error control code for the first data or the second data. The binding section generates third data by binding the second data generated by the data compression section to the error control code generated by the code generation section. The transfer section transfers the third data generated by the binding section to the memory in units of the predetermined data length.
