摘要： Systems and methods are described including dynamically configuring a shared buffer to support processing of at least two video read streams associated with different video codec formats. The methods may include determining a buffer write address within the shared buffer in response to a memory request associated with one read stream, and determining a different buffer write address within the shared buffer in response to a memory request associated with the other read stream.

摘要： CABAC coefficient decoding may be increased to two bins per clock. Since coefficients comprise most of the bitstream, this improvement almost doubles the CABAC decoding for a low quantization parameter bitstream (with lots of coefficients).
摘要翻译： CABAC系数解码可以每个时钟增加到两个bin。 由于系数包括大多数比特流，所以这种改进对于低量化参数比特流（具有大量系数）几乎使CABAC解码加倍。

摘要： Context-adaptive variable length bitstream decoding performance may be improved and power consumption reduced by pushing the variable length decoding beyond one syntax element per clock pulse.
摘要翻译： 可以通过将可变长度解码超过每个时钟脉冲一个语法元素来改善上下文自适应可变长度比特流解码性能并降低功耗。

摘要翻译： 描述了系统和方法，包括动态配置共享缓冲器以支持与不同视频编解码器格式相关联的至少两个视频读取流的处理。 方法可以包括：响应于与一个读取流相关联的存储器请求，确定共享缓冲器内的缓冲器写入地址，以及响应于与另一个读取流相关联的存储器请求，在共享缓冲器内确定不同的缓冲器写入地址。

摘要： Systems, devices and methods are described including using, during a single clock cycle, one Context-Based Adaptive Arithmetic Coding (CABAC) engine to encode one bin value and another CABAC engine to encode another bin value. The probability state index of each CABAC engine may provided to the other CABAC engine when the bin values are encoded.
