FIELD: computer equipment.
SUBSTANCE: technical result is achieved due to operation method of shift register with linear feedback (LFSR) in computer system, including setting of final field P with operation of addition ⊕, a multiplication operation ⊗, zero element θ and unit element e; selecting a computing system having a processor with a SIMD architecture, specifying a natural number n; setting a natural number k, k≤n; setting LFSR in a Fibonacci configuration, setting the number of cycles LFSR – m, where m≥1, m=kν+w, where ν, w are non-negative integers, 0≤w≤k-1; m cycles of LFSR operation.
EFFECT: technical result consists in improvement of productivity of LFSR type Fibonacci when using a computer system, which enables parallel calculation of k identical linear functions of different arguments.
