The objective of this paper is to provide a review of the recent development in HEVC standard with integer DCT with summaries of technological advancement. In this paper, we discuss Integer discrete cosine transform (DCT) of High-Efficiency Video Coding HEVC for video compression. It uses 2D DCT from 4x4 to 32x32 transform with higher precision as compared to h.264/AVC. In this paper, we propose an area efficient and energy efficient VLSI architecture of HEVC. We propose a new efficient Constant Matrix Multiplication scheme (CMM) can be used to find parallel architecture for 1d integer DCT having different length of 4-pt., 8-pt., 16-pt. and 32-pt. with the throughput of 32 DCT coefficient per cycle with respect to transform size. The above architecture reduces the complexity of implementation with slightly effect on the coding performance so we purpose efficient structure with low power called ‘Power Efficient Structure' for full parallel implementation of 2D DCT from the synthesis result. It shows that propose architecture involves less area-delay product (ADP) and less energy per sample (EPS) compare to direct implementation of the reference algorithm for integer DCT. Larger transform requires more computation per coefficient and they contain a non-zero coefficient due to this larger transform can be more energy efficient the proposed architecture is found to support UHD which is one of the applications of HEVC
