What is the Avalon system interconnect fabric?
The Avalon® system interconnect fabric is Altera’s parameterized interface bus used by Nios and Nios II processors. While most processor systems use bus topologies structured around a system bus shared between all peripherals in the system (as well as require designers to spend a large portion of their time verifying that the interfaces of all their peripherals work), the Avalon switch fabric is custom-built to the interface requirements of every peripheral in the system. This means that system designers need only design the interface that their peripheral requires without worrying about the complete set of Avalon switch fabric transactions. The SOPC Builder design tool automatically creates the proper Avalon system interconnect fabric to support each interface of the peripherals present in the system.
