Research ArticleOpen accessIn the keywordsSmooth Formant Peak Via Discrete Tchebichef TransformNur Azman Abu, Ferda Ernawan, Fadzilah SalimWith the growth in computing power, speech recognition carries a strong potential in the near future. It has even become increasingly popular with the development of mobile devices. Presumably, mobile devices have limited computational power, memory size and battery life. In general, speech recognition operation requires heavy computation due to large samples per window used. Fast Fourier Transfom (FFT) is … …Journal of Computer Science, Vol. 11, Issue 2 · 10 Sep 2014 · 7,187 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Reconfigurable Execution Core for Merged DSP MicrocontrollerA. K. Rath, P. K. MeherThe study presents an execution core which can be reconfigured either for calculation of digital convolution or for computation of discrete orthogonal transform by appropriate local buffer initialization of processing cells. It is shown that the data flow pattern can be changed by a single bit control signal. The proposed core can be connected to port 1 of Intel 8051 … …Journal of Computer Science, Vol. 3, Issue 10 · 31 Oct 2007 · 6,483 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign of a Merged DSP Microcontroller for Embedded Systems using Discrete Orthogonal TransformA. K. Rath, P. K. MeherIn this paper we have proposed the design of a DSP microcontroller where the processor load is significantly reduced by relegating the math-intensive DSP algorithm to dedicated transform computing modules. It is shown that the use of such transform modules will facilitate scalability, reusability and flexibility for implementation of wide varieties of DSP functionalities. Moreover, it would be possible to … …Journal of Computer Science, Vol. 2, Issue 5 · 31 Aug 2006 · 6,918 accessesView PDFCite
