Abstract

Styrefunksjoner er integrerte i digltalsignal- behandlings-(DSP)-chip-funksJoner som sentralproses- sorenhet (CPU) for abonnentens celleoppdelte telefonenhet, som eliminerer mikrostyreren og andre understøttende chips. Den tilveiebragte integrasjonen er ikke en fysisk integrasjon som kombinerer DSP og mikrostyre- chipsene til en enkelt chipsarkitektur, men istedet en logisk (dvs. programvare) integrasjon. En sanntids- okkupering av utførelsen styrer utførelsen av for- skjellige funksjoner og meldinger mellom dem. Mengden med kode som må kjøres på DSP-chipen, som virker på CPU'en, er større enn adresserommet til DSP-chipen slik at kodelageret er delt i databanker med kun en bank aktivert om gangen. Det er oppgaven til sanntids- utføreren å aktivere databankene nødvendig for å styre de forskjellige funksjoner.
