Abstract
A device and a method for forming a signature, a predefined number of shift registers being provided, to which input data to be tested is applied bit-by-bit and in parallel as successive data words and which serially shift the input data forward in a predefinable cycle, a signature being formed in the shift registers after a certain number of data words and cycles, a code generator which generates at least one additional bit position in at least one additional shift register from each data word in the signature also being provided.
Claims10
A device for forming a signature, comprising:
- a shift register having a predefined number of bit position memory devices, to which input data to be tested is applied bit-by-bit and in parallel as successive data words and which serially shift the input data forward in a predefined cycle, a signature being formed in the bit position memory devices after a predefined number of applied data words and cycles;
- and
- a code generator which generates at least one additional bit position in at least one additional bit position memory device of the shift register from each applied data word in the signature.
A method for forming a signature, comprising:
- providing a shift register having a predefined number of bit position memory devices, to which input data to be tested is applied bit-by-bit and in parallel as successive data words and which serially shift the input data forward in a predefined cycle, a signature being formed in the bit position memory devices after a predefined number of applied data words and cycles;
- and
- providing a code generator which generates at least one additional bit position in at least one additional bit position memory device of the shift register from each applied data word in the signature.
