Abstract: XAPP228 Application Note: Virtex-II and Spartan-3 Series R Wider Block Memories Author: Nick Sawyer, Marc Defossez XAPP229 (v1.1.1) April 19, 2007 Summary This application note describes how memories wider than 36 bits can be efficiently implemented in the VirtexTM-II and SpartanTM-3 generation architectures. The clock doubling method used is similar to the method described for quad-port memories in XAPP228. The resulting memories are used in either dual-port or single-port mode. Introduction Ever
