SOPC Builder is an Altera tool for creating bus-based (especiallymicroprocessor-based) systems in Altera devices. SOPC Builderassembles library components like processors and memories into custommicroprocessor systems.SOPC Builder includes the active serial memory interface (ASMI)peripheral, an interface core specifically designed to work with the serialconfiguration device. Using this core, you can create a system with a Niosembedded processor that allows software access to any memory locationwithin the serial configuration device.fFor more information on accessing memory within the serialconfiguration device, see the Active Serial Memory Interface Data Sheet.Altera Corporation 4–7April 2007 Configuration Handbook, Volume 2
