if you want to receive G-code over ethernet, interpret it, show it on screen, and run a machine you need a lot of the software components that are already there in place with a linux+EMC2 solution.
IMO working on an fpga-based kick-ass I/O module for the beagle-board would be time more well spent.

sending G-code to a microcontroller over ethernet, displaying it on the LCD, and interpret-it (G00 and G01) in microcontroller is allready done.
I will use FPGA only to escape from microcontroller limitations.

if I've understand right, beagle-board is a small computer, based on CPU and memory. This architecture is not favorable to this embedded system.

Cypress is bringing out a PSOC 5 chip next year with ARM cortex M3 & on board analog & digital peripherals.

As for FPGA - what MCU will you use ?

Are you coding verilog or VHDL ?

I nearly have my electronics degree now & have a diploma in control systems.

Why not just stick LINUX into your chip and run a LINUX g-code app ?

I have an altium development board.
