摘要： An audio/visual (A/V) system utilizes a software architecture partitioned between application specific code and common processing code. For example, in an audio context, decoder code represents an embodiment of application specific code and post-processing operations such as bass control, tone control, volume control, and mute represent common processing code. The A/V system also utilizes a RISC processor to control communication between a digital signal processor (DSP) and peripheral devices. A/V system 300 uses a first-in-first-out (FIFO) memory buffer to store communications between the RISC processor and DSP. The FIFO is preferably sufficiently large to allow the RISC processor and DSP to operate at their own respective paces. A/V system 300 also utilizes a standard command word and a manager for each DSP application that allows the RISC and DSP to easily exchange information.

摘要： A method of processing a stream of encoded units of data samples includes the step of calculating a sample advantage using timing information embedded in selected ones of the encoded units, the sample advantage representing a time difference in number of samples between the presentation of a reference sample and the availability of the reference sample. A number of phantom samples substantially equal to the number of samples represented by the calculated sample advantage are queued and then output from the queue at a selected rate. Substantially simultaneous with the outputting of the phantom samples from the queue, at least some data samples of at least one encoded unit are decoded and queued behind the phantom samples.

摘要： A method for transferring data bursts via a synchronous data link includes the step of receiving a burst of packets, each packet including a header and a frame of data compressed at a selected sampling rate and transmitted at a selected bit rate. At least one of the packets of the stream of packets is embedded into a carrier frame including a carrier frame header. The carrier frame is then transmitted via the synchronous link. The data frame is extracted from the carrier frame and decompressed at the sample rate.

摘要： A method of decoding an encoded bitstream. The method includes performing a two-table lookup. A first table is addressed in response to a first plurality of bits from the bitstream. An address into a second table is generated using a value in an entry in said first table accessed in the addressing step. A value (representing the decoded value corresponding to the codeword in the bitstream) in an entry in said second table at the address from the generating step is output.
摘要翻译：一种对编码比特流进行解码的方法。该方法包括执行两表查找。响应于来自比特流的第一多个比特来寻址第一表。使用在寻址步骤中访问的所述第一表中的条目中的值来生成到第二表中的地址。输出在生成步骤的地址处的所述第二表中的条目中的值（表示对应于比特流中的码字的解码值）。
