In this paper, a robust vowel-like speech (VLS) detection method using modified non-local means normalization factor (MNLM-NF) and it’s FPGA prototype is proposed. In the original NLM algorithm, at each instant of time, the NLM-NF is estimated by accumulating the weight values (WVs) computed over the search neighborhood. During the computation of WVs, one frame is kept as fixed while the other frame...
This paper presents the fast carry chain adder using Instantiation design entry which facilitates the direct design of the components through exact placement of the individual blocks in FPGA. The basic n-bit adder is divided into n/3 number of ripple carry adders with carry inputs generated from separate carry generator. The carry generator is designed on LUT by using all the six inputs with 100%...
