Abstract: A method for detecting faults in substring search operations includes providing, using a processor unit including vector registers of M vector elements each, anMxM Matrix of comparators for characterwise comparison of the elements of a reference string stored in a first one of the vector registers and a target string stored in a second one of the vector registers. A vector element is an n-bit element for encoding a character.A resulting bit vector is generated using comparison performed by the MxM matrix. The resulting bit vector indicates characters of the target string that fully match the reference string and indicates characters of the target string that partially match the reference string. Fault detection in the substring search operations is performed by utilizing the resulting bit vector.
