An interface between synchronous and asynchronous data transfer includes a plurality of stages coupled to each other to form a pipeline for data transfer. The plurality of stages include a first stage which performs synchronous to asynchronous data transfer, at least one intermediate stage which performs asynchronous to asynchronous data transfer and a last stage which performs asynchronous to synchronous data transfer. A synchronous clock path propagates a timing signal across the plurality of stages to enable the first and last stages to perform operations when the timing signal is present at that stage.
L'invention concerne une interface entre un élément de transfert de données synchrone et asynchrone, comprenant une pluralité d'étages couplés les uns aux autres pour former un pipeline destiné au transfert de données. Cette pluralité d'étages comprend un premier étage qui effectue le transfert de données synchrone-asynchrone, au moins un étage intermédiaire qui effectue le transfert de données asynchrone-asynchrone et un dernier étage qui effectue le transfert de données asynchrone-synchrone. Une voie de synchronisation synchrone propage un signal de synchronisation à travers la pluralité d'étages pour permettre au premier et au dernier étage d'effectuer des opérations lorsque le signal de synchronisation est présent à cet étage.
