Abstract:
1. A control apparatus comprising: a first code generation part for generating a first error detection code from first information which is output as a result of execution of a predetermined program conducted by a first processor; a second code generation part for generating a second error detection code from second information which is output as a result of execution of the program conducted by a second processor configured so as to output a same computation result as the first processor; a comparison control part for detecting whether the first information is same as the second information, detecting whether the first error detection code is same as the second error detection code, and controlling writing the first information or the second information into a main memory on a basis of a result of the detection; and a correction code generation part for generating an error correction code on a basis of either the first information or the second information and either the first error detection code or the second error detection code when the comparison control part has detected that the first information is the same as the second information and the first error detection code is the same as the second error detection code; wherein the correction code generation part controls writing the error correction code generated on a basis of a result of the detection conducted by the comparison control part, into the memory.
