摘要

This paper presents a unified systolic architecture for inter and intra predictions in H.264/AVC decoder. To increase hardware utilization and minimize cost, we combine inter and intra predictions by a reprogrammable FIR filter, which is further implemented using systolic array. For intra prediction, the boundary pixels are reshuffled before feeding into the systolic array. For inter prediction, the 2-D interpolation is conducted through separable 1-D filtering. As compared with the state-of-the-art approaches, our architecture provides higher performance while maintaining relatively lower cost and input bandwidth. Specifically, up to 4× throughput improvement has been achieved. Moreover, the input bandwidth is significantly reduced. Further, combining inter and intra predictions saves the cost by 22-88%.
