Abstract

Oppfinnelsen angår en fremgangsmåte og en anordning for å forbinde en prosessor med en ASIC. l anordningen genererer prosessoren styringssignaler som benyttes når prosessoren leser data fra og skriver data inn i ASIC-en. Anord- ningen omfatter midler (10) for å motta styringssignaler fra prosessoren og gene- rere lese- og skrivesignaler på grunnlag av de mottatte signalene. Midlene (10) implementeres ved hjelp av en asynkron tilstandsmaskin som forandrer sin til- stand på grunnlag av de mottatte signalene. Midlene (10) forandrer sin tilstand uten et synkroniserende taktsignal.
