Interfacing and programming ROM AT25512

Hello,

I'am beginner with FPGA. I design prog to treat images who work. To do it, I integrated ROM with small images in my VHDL program and it works perfectly. However, VHDL ROM is now too large too big with images inside and doesn't fit MAX10M08.

So now I must use external ROM to store images samples that I must display (always the same). I connect ROM AT25512 (ROM I have) to standard SPI signal of the chip /CS, /DO,/DEVCLR(/WP), nSTATUS, CLK and DI.

I have 2 questions :

1. I don't see any IP to interface SPI ROM such as AT25xxx ?

2. is that possible to dump ROM images directly from JTAG. I mean from Quatrus programmer tool by loading in one POF file 'FPGA program' and in second XX file ROM images directly to PROM ?

Thanks for your answers and help

Regards,

OL
