| 摘 要： | 离散余弦反变换(IDCT)广泛应用于MPEG-4等视频压缩、解压缩应用中。在嵌入式系统中,IDCT运算的效率将直接影响MPEG-4实时解码性能。文中根据嵌入式系统的特点,提出了一种新的IDCT硬件实现方法,并采用了一种新的验证手段对该硬件实现进行了全方位的验证。该方案已经应用于一款SoC芯片中的硬件MMA(多媒体加速单元)中。 |

| Abstract: | IDCT is an important computing process and used in MPEG-4 decoding.In employment of SoC to do the MPEG-4 decoding,IDCT computation efficiency will impact the whole decoding performance because of the restriction of the ability of computing the SoC core.In this paper,we present a new realization method of IDCT and a new method to carry out the verification.This kind of realization has been used in a MMA module of a SoC. |
