Zusammenfassung:	A programmable modem ( 20 ) for processing a waveform includes a general purpose processor (GPP) engine ( 34 ) and special purpose programmable signal processing engines ( 22 ) in communication with the GPP engine ( 34 ). Each of the special purpose engines ( 22 ) executes a special purpose software program ( 80 ) to process a portion of the waveform under one of a plurality of communications standards in response to control signals from the GPP engine ( 34 ). A power manager engine ( 56 ) is in communication with the GPP engine ( 34 ) and the signal processing engines ( 22 ). The power manager engine ( 56 ) responds to the control signals from the GPP engine ( 34 ) to power currently used ones of the special purpose engines ( 22 ) and to discontinue power to unused ones of the special purpose engines ( 22 ). The programmable modem is implemented on a single CMOS integrated circuit ( 66 ).
