The present invention provides a bus to bus interface unit for computer systems having dual bus architecture, such as a system bus and an I/O bus. The bus interface unit includes an asynchronous bidirectional temporary data storage function for data being transferred between the two buses to and from devices coupled to each of the two buses. Preferably the storage function operates in modes that will accommodate individual transfers of data, data streaming, and data burst transfers, and can accommodate transfers of information from contiguous addresses without initiating a new request for each address.
Unité d'interfaçage de bus à bus pour systèmes informatiques à deux bus, p. ex. un bus système et un bus E/S. Comprend une fonction de stockage temporaire bidirectionnel asynchrone de données transférées d'un bus à l'autre à destination et en provenance de dispositifs couplés à chacun des deux bus. De préférence, le stockage se fait suivant des modes qui permettent les transferts individuels de données, les flux de données et les transferts de paquets de données, et peuvent permettre les transferts d'information à partir d'adresses contiguës sans lancer une nouvelle demande pour chaque adresse.
