    Abstract: The present invention provides a non-binary Viterbi data processing system comprising a non-binary Viterbi processor, a path metric memory, and a memory access device. The non-binary Viterbi processor is used for obtaining the path metrics of a set of states according to a Viterbi decoding procedure. The path metric memory comprises memory units of the same amount as the states. The memory units are depicted by combinations of symbols for storing the corresponding path metrics of the set of states. The memory access device is used for reading out the path metrics from the path metric memory for calculation by the non-binary Viterbi processor, and for writing the updated path metrics back to the path metric memory. Therefore, merely the same amounts of the memory units as the states in the path metric memory are required for update of the set of path metrics.

    Abstract: The present invention relates to an audio data synthesis system for sequentially processing a first predetermined number of audio data to synthesize a digital audio signal cumulatively. The system comprises a first memory, a first processor, an audio data processing unit, and a second memory. The first memory is for storing a plurality of audio data. The first processor is for generating an audio processing request for requesting to process a second predetermined number of audio data. The audio data processing unit is for receiving the audio processing request, accessing the second predetermined number of audio data stored in the first memory, and calculating every two neighboring audio data to get data processing values, and after calculating all the second predetermined number of audio data, then obtaining a third predetermined number of data processing values. The second memory is for storing the third predetermined number of audio data.
