ABSTRACT: The promising High Efficiency Video Coding (HEVC) standard aims at much higher coding
efficiency, but the cost is the greatly increased computation complexity. Among all the coding modules, DCT
and IDCT are frequently called and bring a lot of complexity burden. While, the Single Instruction Multiple
Data (SIMD) technique has been widely used to speed up media data process. In this paper, we focus on SIMD
acceleration ...
