Abstract

Et effektivt konfigurerbart signalfilter (52). Filteret (52) innbefatter en første mekanisme for å motta et første signal av en første type og et andre signal av en andre type. En andre mekanisme (60, 61) filtrerer selektivt det første signalet under den første driftsmodus og filtrerer det andre signalet under en andre driftsmodus. En tredje mekanisme (68) danner styringssignaler. En fjerde mekanisme (64, 68) konfigurerer automatisk den andre mekanismen til å arbeide i den første driftsmodusen eller den andre driftsmodusen basert på styringssignalene. I en spesifikk utførelsesform karakteriseres den første signaltypen av en første hastighet, og den andre signaltypen er karakterisert ved den andre hastighet. Det første signalet og det andre signalet er digitale ADC utmatinger. Den andre mekanismen (60, 62) innbefatter et flertall av filterblokker som hver har en eller flere multipliser-akkumuler (MAC)-blokker. Hver av de en eller flere MAC-blokkene innbefatter en eller flere MAC-paiper som hver er forbundet med en koeffisientminne datastruktur av et koeffisientminne (64). Den tredje mekanismen (68) eller en bruker velger koeffisienter fra hver minnedatastruktur for å anvendes på hver MAC-blokk, hvorved selektivt påvirker signalresponsen. Styringssignalene ordner multiplekserne eller svitsjene til å konfigurere MAC-paipene i en seriell konfigurasjon eller en parallell konfigurasjon motsvarende henholdsvis den første driftsmodusen eller den andre driftsmodusen.
