摘要: Presented herein is a unified decoder architecture. A system comprises a video decoder, instruction memory, and a host processor. The video decoder decodes the video data encoded with the particular standard. The instruction memory stores a first set of instructions and a second set of instructions. The first set of instructions are for decoding encoded video data according to a first encoding standard. The second set of instruction are for decoding encoded video data according to a second encoding standard. The host processor provides an indication to the video decoder indicating the particular encoding standard. The video decoder executes the first set of instructions if the indication indicates that the particular encoding standard is the first encoding standard and executes the second set of instructions if the indication indicates that the particular encoding standard is the second encoding standard.

摘要: Presented herein is a direct memory access engine for providing data words in the reverse order. The data words are fetched in batches comprising a predetermined number of data words starting from the last data word and proceeding to the first data word. The batches are stored in a local buffer. The contents of the local buffer are transmitted in reverse order.
摘要翻译: 这里呈现的是用于以相反顺序提供数据字的直接存储器访问引擎。 数据字被分批地取出,包括从最后数据字开始的预定数量的数据字,并进行到第一数据字。 批次存储在本地缓冲区中。 以相反的顺序发送本地缓冲区的内容。
