Noesis Technologies Announces Availability of CVSD Voice Codec

July 17, 2013 – Noesis Technologies announced today the immediate availability of its CVSD voice codec algorithm compliant IP Core. The fundamental principle of the CVSD algorithm is the encoding of one bit per sample, for example an audio signal sampled at 32 KHz will be compressed to 32 Kbps. The ntCVSD codec IP core can be configured to operate either as an encoder or as a decoder functional block. In encoder mode the core accepts input data at a rate of 8 KHz/128 Kbps or 16KHz/256Kbps and are sampled when the data strobe signal is asserted high. Higher input sampling data rates can also be supported with no up-sampling provision.

Applications

The ntCVSD codec is designed to compress 16-bit PCM speech/audio data for transmission in telecom networks or to decompress a received CVSD encoded bitstream. It is compatible with legacy CVSD implementations and fully compliant with the Bluetooth CVSD specification. The core can be delivered as RTL source code, FPGA or ASIC (GDSII) netlist, under an End-User License Agreement.
