摘要 4×4整数变换是H.264视频压缩标准的关键技术之一,对H.264编解码器的整体性能有重要影响。基于流处理的思想,提出了一种适用于H.264整数变换的混合流式变换算法MSTA,并将其映射到了Imagine流处理器上。实验结果表明,MSTA流实现处理一次4×4整数变换仅需4.5ns,远超出当前实时应用的需求。另外,流处理器良好的灵活性将使MSTA拥有更广阔的应用前景。 The 4*4 integer transform, as one of the key techniques in H.264 video compression standard, is very important for the whole performance of H.264 CODEC. Based on stream processing, a Mixed Streaming Transform Algorithm (MSTA) for 4*4 integer transform in H.264 was proposed and mapped onto Imagine stream processor. Experimental results show that the streaming implementation of MSTA processes a 4*4 integer transform only in 4.5ns, beyond the real-time requirement of current applications. In addition, the stream processors can take advantage of its flexibility to use MSTA widely in the future.
