In this paper proposed power and area efficient discrete cosine transform (DCT) architecture for
multimedia applications. This paper Implemented conventional DCT and multiplier less DCT‟s by less
number of adders/subtracter and multipliers. Area and power achieved by reducing mathematical operations.
Number of cells, cell area, internal power, net power, leakage power, switching power reduced compared to
conventional DCT. Power delay product of both conventional DCT and multiplier less DCT‟s are 19.8mJ,
19.7mJ and 10.8 mJ respectively. The proposed DCT and conventional DCT are implemented on cadence
RTL compiler 180nm.
