ADPCM, 1024 Channel Simplex

"The Amphion family of adaptive differential pulse code modulators (ADPCMs) is designed to provide high performance solutions for a broad range of applications requiring speech compression and decompression. These application specific virtual components (ASVCs) support up to 1024 simplex channels on Xilinx FPGA. Each channel is independently selectable for encoding or decoding, and are fully compliant with ITU G.726, G.726a, G.727 and G.727a standards. The core supports 1024 simplex channels. The core is online configurable in terms of compression rates. It has been tested and verified to be fully compliant using the ITU standard test vectors.
