game using verilog coding and altera de2-70 board with touch screen

Hi Sya:

NIOS is an Altera cpu that is scalable from low performance, small size, to mid performance, and capabilities but with a larger footprint. In ARM cpu terms, think it's capable of ARM Cortex M0 - M4 capabilities. It great for many embedded projects, but doesn't have the performance of the higher end ARM processors like the A9 and above families.

You can attempt to go with a complete verilog solution, and if it's required, you will need to do it.. It is possible.

I have never did any verilog code to run a touch screen strictly from RTL, so I can't help you there.
