摘要：In signal progressing domain, recent days there is bottleneck parameter performance like area, latency.To provide area efficient integer Discrete Cosine Transform (DCT) designs for High Efficiency Video Coding(HEVC). So that invoked CORDIC architecture to produce on fly trigonometric output instead of traditional method. Ininteger DCT have its own style of operation and to calculate twiddle factor of DCT CORDIC architecture activelyintroduced and make sustainable result in area. The computational complexity has been reduced considerably half ascompare to traditional operations. The Experimental result shows that the proposed Dct algorithm has not only reducesthe computational complexity. Significantly, it also keeps the better transformation quality of the efficient integerDCT. Therefore, the proposed CORDIC based integer DCT can be used in area efficient and high speed HEVC systemsespecially in battery-based systems. The design has been verified using Modelsim 6.4se and obtain RTL schematicusing Xilinx 13.1 Ise.
