Quartusii compile

Hi,

I am developing with cycloneIV.

The system contains large IPcores such as ATAN and DDRSDRAM.

It takes a while when I compile the project.

But matter is that when I compiled the project on the other PC.

The process failed because of memory space.

My pc has 8GB with Windows7 64bit OS

the other one os 4GB with WindowsXP 32 bit.

But 4GB is largest number for 32bit OS isn't it?

Do I need 64 bits OS as long as I maintain this kind of system?

    With default settings, under 32 bit Windows XP/Vista/7, applications can't get more than 2GB each.

    If you have a reason not to use a 64 bit OS, there are some options to increase that limit.

    You can increase the limit to 3GB if you use the /3GB option. Check http://support.microsoft.com/kb/833721

    Running on 32 Windows Server, you can get up to 4GB per application (/PAE)

    But if, possible, it's best to move onwards to 64 bit.

    thanks rbugalho.

    actually, I do have 64bit OS. thats OK.

    this is just a question.

    does every engineer have 64 bits?

    that is tough.

    anyway thanks a lot.

    Not yet. But not all of us need it yet.

    In any case, any PC sold nowadays supports 64 bit and, most likely, comes with 64 bit Windows.

    The world is moving quickly towards that.
