Abstract :
The high performance general purpose digital signal processor (DSP) provides a cost efficient solution for a broadband digital subscriber line (DSL) transceiver. A DSL modem with a transmission throughput between 400 kbps and 2 MOPS operating over most of the existing telephone subscriber loops has been implemented on a single TI TMS320c548 DSP for consumer multimedia applications such as Internet access. Except the analog front end (AFE), all the discrete multitone modem (DMT) algorithms are implemented with DSP software. The DSP based software DSL modem also provides a convenient interface to Microsoft point-to-point protocol (PPP) for network access
