Title: Error detective information adding equipment

Abstract: An error-detecting information adding apparatus transfers original data received from an external host apparatus to a memory and to an error-detecting code generating unit in one DMA transfer so that while the original data is transferred to the memory, an error-detecting code is generated. The error-detecting code generated by the error-detecting code generating unit is transferred from the error-detecting code generating unit to the memory.
