ERROR DETECTION APPARATUS FOR SELF-CHECKING COMPUTATION PROCESSING APPARATUS BASED ON SCALABLE ERROR DETECTION CODE, AND COMPUTATION PROCESSING SYSTEM COMPRISING THE ERROR DETECTION APPARATUS

摘要

The present invention relates to an error detection apparatus for a self-checking computation processing apparatus based on a scalable error detection code, and to a computation processing system comprising the error detection apparatus. More particularly, the present invention relates to an error detection apparatus for a self-checking computation processing apparatus based on a scalable error detection code and to a computation processing system comprising the error detection apparatus, the apparatus and the system of the present invention being capable of continuously detecting, by adding a minimum number of pieces of hardware, errors of the self-checking computation processing apparatus, which performs self-checking based on a scalable error detection code, in computation or in generating an error detection code, the apparatus and the system of the present invention being capable of scaling the error detection code by varying the value of the error detection signal regardless of the length of the binary input data as an object of computation and the length of the binary output data as the result of the computation, the apparatus and the system of the present invention being capable of minimizing the amount of time required to detect errors.
