摘　　要：针对图像传输的比特纠错去噪处理高效实现,本文提出了一种基于小波分解的比特纠错SIMDPE阵列数据并行计算方法。该方法,针对不同的小波子带,采用不同的并行计算策略;针对数据并行计算中的PE选择问题,采用PE标识预置的解决方法,即确保去噪效果,又使得数据并行操作更为规则、简洁,大幅度地提高了处理的速度。To achieve highly efficient realization of bit correction denoising process of image frame noised by noisy channel, a kind of SIMD PE array data parallel computation method of bit error correction based on wavelet transform was. In proposed scheme, different schemes of parallel computation are adopted in different wavelet subbands. The method of setting PE identifier in advance is adopted to solve the issue of PE selecting in parallel operation, which not only insures the efficient of denoising, but makes the data parallel operation more regular and compact, greatly improves the processing speed.
