This paper illustrates the simulation of Vedic multiplier in 2-D DCT. The input data is first divided into NxN blocks, each block s of 8x8 size and 2-D DCT is applied on each of these 8x8 block and 2-D DCT is applied to reconstruct the image. The proposed 2-D DCT design uses Urdhva Tiryagbhyam a Vedic multiplication sutra and the Simulations with MATLAB prove that the proposed design is compared to that of conventional design. Performing DCT computations using Vedic multiplication sutras gives a significant performance even compared to a DCT using conventional. To illustrate our approach, the sample code implements part of JPEG compression routine, performs forward DCT on 8x8 blocks, quantizes coefficients, and performs inverse DCT.
