A survey of hardware signature implementations in multi-core systems

Signature is used as a short and unique representation to identify a person. In the similar manner hardware signature is used to identify items like memory locations that got stored in bounded hardware registers in a hashed form. This paper considers bloom filter based hardware signatures and reviews several hardware signature implementations in multi-core systems. Some of the hardware signature implementations don´t require additional hardware and some other implementations require additional hardware. There are better replacements for hardware signatures like memory snapshot technique with other kinds of overheads. Hardware signatures will lead to false conflicts whereas memory snapshot technique leads to hardware overhead.
