It could be done in less than a day, even a couple of hours, for an 'experienced' VHDL engineer, a novice would take of course longer but not months, even if you are a beginner in VHDL. As you indicate the 'suggestion' schematic in the i2s specification (www.nxp.com/acrobat_download2/various/i2sbus.pdf) doesn't look that difficult.

I don't see much relevance in AN487 though. Converting an I2S into a SPI doesn't really make sense I'd say.

What ADC(s) are you using?
