// Filename: ax7325b_ddr3.v
|
||||
// Project: UberDDR3 - An Open Source DDR3 Controller
|
||||
//
|
||||
// Purpose: Example demo of UberDDR3 for AX7325B FPGA board from ALINX (xc7k325tffg900-2).
|
||||
// Mechanism:
|
||||
// - four LEDs will light up once UberDDR3 is done calibrating
|
||||
// - if UART (9600 Baud Rate)receives small letter ASCII (a-z), this value will be written to DDR3
|
||||
// - if UART receives capital letter ASCII (A-Z), the small letter equivalent will be retrieved from DDR3 by doing
|
||||
// - a read request, once read data is available this will be sent to UART to be streamed out.
|
||||
// THUS:
|
||||
// - Sendng "abcdefg" to the UART terminal will store that small latter to DDR3
|
||||
// - Then sending "ABCDEFG" to the UART terminal will return the small letter equivalent: "abcdefg"
|
||||
//
|
||||
// Engineer: Angelo C. Jacobo
