Low cost FPGA SDRAM Controller

Design a circuit and program VHDL for low cost SDRAM controller using FPGA:

Requirements:

1) Can use single slot standard PC133 SODIMMs 2GB notebook memory with

standard SODIMM slot

2) Operates as? SPI SDRAM (same design as? Microchip 32kbyte SPI SRAM? <[url removed, login to view]>? except 32bits to support 2GB of memory)

3) Has SPI interface (CS, CLK, DI, DOUT) with following commands:

OP CODE + Address + DATA

OP Codes:

00 -read register

01 -write register

Address: 32bits

DATA: 32bits

32 bit Registers:

Address: 0x00 Status

4) 6 pin interface with 2x3 .1" headers

pin 1: +[url removed, login to view]

pin 2: GND

pin 3: DI

pin 4: DOUT

pin 5: CLK

You should? can use free open IP FPGA Core for SDRAM and IP core? interface and just make supporting circuit.
