MIG 7 Series and Virtex-6 DDR2/DDR3 Solution Center Design Assistant - Interfaces


The MIG 7 Series andVirtex-6 FPGA DDR3/DDR2 design is divided into three main pieces - User Interface, Controller, and PHY. This Controller is the middle piece of the design and therefore interfaces to both the User Interface and the PHY. On the other side, the controller interfaces to the User Interface through what is called a Native Interface. This is a low latency interface that does not include any FIFOs to organize the commands and data. The Native Interface can then (optionally) interface to the true User Interface where data and commands are stored and organized in FIFOs. Between the Native Interface and the PHY is called the PHY Interface. Through this interface the user bypasses the Memory Controller altogether and can send memory commands and data directly through the PHY interface .
