【摘要】 提出了两种不同的,基于DSP芯片TMS320VC5502的,具有并行运算特点的5/3小波提升方法的硬件实现方案;并且分析了两种方案的效率差异。实验证实,两种方案均明显缩短了对图像数据进行离散小波变换的时间。更多还原

【Abstract】 Two arithmetics with parallelism features for performing lifting based JPFG2000’ s 5/3 Discrete Wavelet Transform are proposed in this paper,which are performed on the digital signal processor TMS320VC5502.And it compares the two arithmetics’ efficiency in advance.The experiment demonstrates that both arithmetics can reduce the amount of time requirement.更多还原
