Parametrizeable ADPCM IP Core
ADPCM (Adaptive Differential Pulse Code Modulation) is used for speech compression of 64 kbit/s PCM data. The ADPCM algorithm is standardized as ITU standard G.721 and G.726. Fields of application range from classical voice based telecommunication (POTS) to industrial speech storage or speech output systems. The advantage of ADPCM is the compareable small computation effort required while delivering very good speech quality.
Our parametrizeable ADPCM IP core is technology independent and may thus be used for FPGA as well as for ASIC designs. The ADPCM IP core is parametrizeable in the number of channels to be processed. The format of the PCM signal may be defined either on a per channel basis or globally. For reducing the complexity one may skip to synchronous coding adjustment unit. This is useful for many industrial and consumer solutions.
