“…where n x is an input signal, k b are filter coefficients, N is a filter order, n y is an output signal [20]. The formula (5) shows that for FIR filter uses only the operations of addition and multiplication, which allows to use only positive features of RNS when designing the filter.…”

The paper presents the results of investigation of RNS moduli set selection effect on the digital filters performance in satellite communication systems. Parks-McClellan filters with the order from 8 to 63 and 7 the most balanced RNS moduli sets were investigated. It is shown which of the considered moduli sets provide the best performance for such systems. Simultaneously difference in performance between the various moduli sets can be up to 32%.

This paper proposes a new approach to the implementation of Finite Impulse Response (FIR) filters in the Residue Number System (RNS). The essence of the method is to use the two-stage RNS, wherein uses two RNS: first RNS for transforming the input signal, and the second RNS for transforming of computational channels of the first RNS. This approach significantly reduces bit width of data, however, it requires to perform additional operations of forward and reverse conversion. Nevertheless modeling of FIR filters using the proposed architecture showed reducing the processing time in comparison with the known analogues.

“…Consequently, the critical path delay, area, and power consumption may simultaneously reduce, leading to faster and more efficient circuits. RNS arithmetic is especially effective in digital signal and image processing applications [10,11]. * This research was supported by Polish Narodowe Centrum Nauki, NCN.…”

In this paper, we present a new residue number system (RNS) {2 n − 1, 2 n , 2 n + 1, 2 n+1 + 1, 2 n−1 + 1} of five wellbalanced moduli that are co-prime for odd n. This new RNS complements the 5-moduli RNS system proposed before for even n {2 n − 1, 2 n , 2 n + 1, 2 n+1 − 1, 2 n−1 − 1}. With the new set, we also present a novel approach to designing multimoduli reverse converters that focuses strongly on moving a significant amount of computations off the critical path. The synthesis of the resulting design over the ST Microelectronics 65nm LP library demonstrates that the delay, area, and power characteristics improve the performance and power consumption of the existing complementary 5-moduli set.
