Description: 用ＶＨＤＬ实现dct．离散余弦变换(DCT)在图像编解码方面应用十分广泛,至今已被JPEG、MPEG1、MPEG2、MPEG4和H26x等国际标准所采用。由于其计算量较大,软件实现往往难以满足实时处理的要求,因而在很多实际应用中需要采用硬件设计的DCT处理电路来满足我们对处理速度的要求-Using VHDL implementation dct. Discrete cosine transform (DCT) in image decoding application of very extensive, has been JPEG, MPEG1, MPEG2, MPEG4, and H26x adopted international standards such as. Because of its large amount of calculation, software is often difficult to meet the requirements of real-time processing, which in many practical applications need to use the hardware design of the DCT processing circuits to meet the requirements of our processing Platform: |
