Macroblock-level decoding and deblocking method and its pipeline implementation in H.264 decoder SOC design

This paper presents a macroblock-level (MB-level) decoding and deblocking method for supporting the flexible macroblock ordering (FMO) and arbitrary slice ordering (ASO) bit streams in H.264 decoder and its SOC/ASIC implementation. By searching the slice containing the current macroblock in the bit stream and switching slices correctly, MBs can be decoded in the raster scan order, while the decoding process can immediately begin as long as the slice containing the current MB is available. This architectural modification enables the MB-level decoding and deblocking 3-stage pipeline, and saves about 20% of SDRAM bandwidth. Implementation results showed that the design achieves real-time decoding of 1080HD (1920×1088@30 fps) at a system clock of 166 MHz.

中医坐浴器结合中药熏洗治疗痔180例疗效观察

为观察中医坐浴器结合中药熏洗治疗痔的临床疗效,选取180例痔患者为观察对象,均采用中医坐浴器结合中药熏洗治疗,观察其临床效果及并发症情况。结果显示,治愈133例,好转47例,无效0例,总有效率为100%。治疗过程中无头晕恶心、皮肤过敏、疼痛及出血等并发症发生,随访3个月至1年,无复发。结果表明,中医坐浴器结合中药熏洗治疗痔操作简单,疗效确切,患者无痛苦,不影响工作,无并发症及后遗症,值得临床推广应用。
