OVERVIEW

The ADSP-2192 dual-core fixedpoint 16-bit DSP is the highest performance DSP for multichannel applications and the first member of the new ADSP-219x DSP family. The ADSP-2192 is the first 16-bit DSP to combine two ADSP-219x cores with industry standard PCI, USB, and AC’97 system interfaces, to make the design challenge easier.
