It significantly reduces the number of equations and as a consequence gives the opportunity to simplify the process of synthesis, factorization and realization of multichannel filter banks and multiwavelet transforms.Item Results of galois field elements multipliers structural complexity evaluation(Видавництво Львівської політехніки, 2013) Hlukhova, AlexandraScalable multiplier for Galois field GF(2m) elements core generator operation is examined. The multiplier uses type 2 Gaussian normal basis for Galois field elements presentation and forms m-bit (m≤998) result by n-bit portions. Generated cores hardware complexity allows their implementation in FPGA for any m and n values. But for big m and n values implementation is impossible because of high structural complexity. The method for such multipliers structural complexity estimation is proposed in this work and results are discussed.Item Multiprocessor system on chip based on programmable processor cores Nios II Altera(Видавництво Львівської політехніки, 2013) Klymenko, Iryna; Storozhuk, AlexanderThe features of a standard design flow facilities SOPC Builder Altera to develop multiprocessor systems are considered.
