Abstract

Digitalt audiobehandlingssystem som omfatter en tidsmultiplekset buss (70; 50) for distribuering av dataverdier i tidsluker (S]-Sfvi); en første inngang for mottak av en sekvens av første dataverdier som representerer en første audiosignalsekvens med en første samplingsfrekvens; en andre inngang for mottaking av en sekvens av andre dataverdier som representerer en andre audiosignalsekvens med en andre samplingsfrekvens; en første signalprosessor som er anvendbar for å behandle signalsekvenser som har den første samplingsfrekvensen; og en andre signalprosessor som er anvendbar for å behandle signalsekvenser som har den andre samplingsfrekvensen; en styreenhet (210) som indikerer første tidsluker på bussen for dataverdier assosiert med den første samplingssekvensen (fsgi) og som indikerer andre tidsluker på bussen for dataverdier assosiert med den andre samplingsfrekvensen, slik at den første signalprosessoren kommuniserer med den første inngangen via de første tidslukene, og den andre signalprosessoren kommuniserer med den andre inngangen via de andre tidslukene.Digital audio processing system comprising a time multiplexed bus (70; 50) for distributing data values in time slots (S] -Sfvi); a first input for receiving a sequence of first data values representing a first audio signal sequence having a first sampling frequency; a second input for receiving a sequence of second data values representing a second audio signal sequence having a second sampling frequency; a first signal processor useful for processing signal sequences having the first sampling frequency; and a second signal processor useful for processing signal sequences having the second sampling frequency; a controller (210) indicating first time slots on the bus for data values associated with the first sampling sequence (fsgi) and indicating second time slots on the bus for data values associated with the second sampling frequency so that the first signal processor communicates with the first input via the first time slots , and the second signal processor communicates with the second input via the other time slots.
