摘要:
Machine-readable media, methods, and apparatus are described to stream data between a codec and a buffer in system memory and to maintain a value in system memory that is indicative of a current position in the buffer. In some embodiments, an audio controller streams the data across an isochronous channel having relaxed ordering rules to the buffer in the system memory and updates the value indicative of current position via a write across the isochronous channel to the system memory.
摘要(中):
描述了机器可读介质,方法和设备以在编解码器和系统存储器中的缓冲器之间流式传输数据,并在系统存储器中维持指示缓冲器中当前位置的值。 在一些实施例中,音频控制器通过具有宽松排序规则的同步信道将数据流式传输到系统存储器中的缓冲器,并且经由跨越同步信道写入系统存储器来更新指示当前位置的值。
