摘　　要：针对JPEG编码这一典型应用,结合ARM同构多核架构特点,基于JFIF数据交换格式语法层可并行化特点提出一种JPEG并行编码策略。实验结果表明,该方法可以显著提升JPEG编码效率,适用于大分辨率及实时性要求较高的图像压缩应用,同时为视频的并行编码提供了参考。In this paper, aiming at the typical application of JPEG encoding, a parallel encoding strategy based on JFIF data interchange format syntax combined with the characteristics of the ARM MPcore structure is proposed. The experiment results show that the pro posed method can significantly improve the efficiency of JPEG encoding, which is suitable for the high resolution and real-time require ments of image compression applications. It provides a certain reference for the video parallel encoding.
