hello, I must bring s.o. Android on the Cyclone FPGA 2. You can do this? If so, how? thank you

I'm not an Android expert, but I'm guessing this is a huge task. First you will need to put a CPU soft core in the FPGA. Android is designed to run on ARM cores, so I think putting an ARM IP core would make the job easier than using Nios II, which would require a complete port of the kernel. But in any case you will still need to write the drivers for all the hardware that you put around the CPU. You must also take into account that the CPU in the FPGA will run a lot slower than a hardcore CPU, and any entry-level smartphone will have a much better performance under Android that a solution based on a Cyclone II.

So the basic Android sources should be not too much tied to the ARM. OTOH ARM is a lot more similar to NIOS than X86 is, so using an ARM port as a basis seems appropriate. -Michael

AFAIK only a small Cortex is available for implementation in an FPGA. I suppose same does not have an MMU. I suppose porting Android to a no-MMU system will be harder than porting it to NIOS with MMU. -Michael

I just read that there is an Android port for MIPS. As NIOS is similar to MIPS this might provide another pointer...

I think the most difficult part is to port the 'dalvik' virtual machine. And we need to port new IPC mechanism.

Dear Kazu,

How do we go about with current nios2linux distribution to be able to run Android, at least on NEEK just as a proof of concept?

I am a bit confused with information in nioswiki and yours regarding Linux + MMU.
