The high throughput required by Motion Estimation (ME) part in H.264/AVC High Definition TV (HDTV) real-time application is very difficult to achieve. Currently one kind of the solutions to this problem is multipling the processing element (PE) array to construct redundant PE array structure. Although redundant structure can take adavantages of parallel processing to achieve high throughput, meanwhile it bring in linear increasing of hardware cost. In this paper, a hardware/software co-solusion is proposed to achieve the required throughput of ME part in H.264/AVC HDTV realtime application. In software side, one adaptive search range (ASR) algorithm which is previously proposed by us [12] is firstly introduced and then experimentally proved can improve the throughput 11.48 times averagely in HDTV1080p video sequence. In hardware side, a previously proposed architecture called SAD-tree [17] is firstly introduced. Then based on this architecture, optimization that increase the frequence is proposed. The hardware implementing result of the optimized architecure shows the proposed optimization can triple the frequence. Finally, it is illustrated that the hardware/software co-solution can help to achieve the required throughput.
