| 摘 要： | 提出一种新的基于行列变换结构的2-DCT／IDCT误差模型。利用该模型得到的计算2-DCT／IDCT的误差公式，能够告知2-DCT／IDCT结构各部件的字长对整体计算的误差贡献。本文根据该误差模型，具体计算了基于行列变换结构的既符合IDCT有穷字长标准，又能够尽可能降低硬件开销的2-DCT／IDCT各部件字长，为所有采用该类结构的设计提供了参照。 |

| Abstract: | The paper gived a novel 2 DCT/IDCT error module which support transform matrix architecture. A error formula is given by making use of the error module.According to the formula, the error contribution of every part of the 2 DCT/IDCT architecture can be known, what's more, the paper calculates every part's word length by trade off both satisfying the standard of IDCT finity word length and the hardware cost, the result can be treated as the reference of the kind architecture design. |
| Keywords: | 2-DCT/IDCT error module row-column transform |
