This implementation of Dual Tone Multi Frequency (DTMF) Generator has been highly optimized to run on the Analog Devices’ Blackfin processor family. It is a self-contained software module that is designed to be compliant with the Q.23 ITU specification for push-button telephone sets. It has been rigorously tested for all digits and keys on the telephone.
It contains a standard C-callable API. The code has been implemented using Instruction and Data cache, and has no dependencies on processor peripherals or registers. This makes system integration much easier.
