A Mixed-Mode Signal Processing Architecture for Radix-2 DHT
Journal Title: International Journal on Computer Science and Engineering - Year 2011, Vol 3, Issue 6
Abstract
This paper proposes a mixed-mode signal processing architecture for radix-2 DHT. In the known algorithms, the stage structures perform all the additions and multiplications. The proposed algorithm introduces multiplying structures which perform all the multiplications with the cosine coefficients and their related additions. This leads to i) simplification of the stage structures which now perform only the additions, and ii) a reduction in the number of multiplications without affecting the number of additions. A mixed-mode signal processing architecture to implement the algorithm utilizing an N-bit ring counter, sample-and-hold array and analog block structure is proposed. The validity of this design has been tested by simulating it with the help of Orcad PSpice.
