The emergence of programmable graphics processing units (GPU) has led to increasing interest in off-loading numerically intensive computations on to graphics hardware. DCT\/IDCT is widely adopted in modern image\/video compression standards and is usually one of the most computationally expensive parts. We present several techniques for efficient implementation of DCT\/IDCT on generic programmable GPU, using direct matrix multiplication. Our experimental results demonstrate that the speed of IDCT on a GPU using the proposed techniques can well exceed that on a CPU with MMX optimization.<\/p>\n","protected":false},"excerpt":{"rendered":"
