shift register

[′shift ‚rej·ə·stər]
(computer science)
A computer hardware element constructed to perform shifting of its contained data.

shift register

A high-speed circuit that holds some number of bits for the purpose of shifting them left or right. It is used internally within the processor for multiplication and division, serial/parallel conversion and various timing considerations.

The configuration of a linear feedback shift register with n states may be based on a polynomial (named characteristic) p(x) = 1 + [c.
A linear feedback shift register can be used for normal polynomial operations: additions, subtractions, multiplications and divisions.
According to Los Alamos researcher and principal investigator Matt Newell, the new multiplicity shift registers are needed because existing devices are nearly 10 years old and becoming incompatible with other detection technology used by the IAEA.
