NIOS II Sim
Jerry - 2004-08-19 21:09:00
I replaced my NIOS I with a NIOS II and did a simulation. Hummm it seems
to take a lot more CPU time with a NIOS II. Has anyone else experienced
this?

Basic questions about the Nios II.
NickNitro - 2007-09-27 00:34:00
Hello.
I'm getting a better outline of what's available and the differences
between the different options, such as FPGAs and CPLDs. Although, I've
just come across Alteras "Nios II Embedded Processor" and to be honest
it's thrown me off completely.

to support Nios II ?

Peter Sommerfeld - 2005-04-27 23:53:00
Hi,
Awhile back I tried having Nios II and a separate cygwin (from
cygwin.com) on the same machine, but ran into big problems. I now want
to install the latest Nios II eval kit but I'm not sure if Altera has
fixed things so they can co-exist.
Does anyone have a stand-alone Cygwin and Nios I...Nios II = Microblaze
Stifler - 2004-05-24 16:56:00
Altera finally wakes up. They realize that the window register type
architecture is not good for FPGAs and probably in general. They can
no longer support their own marketing hype about how great Nios I is.
If Nios 1 was so great, why did it need a complete redesign and
rearchitecture? It means ...Nios memory
cruzin - 2004-01-13 19:36:00
I have an SRAM controller Avalon slave we created which Nios can
successfully access to read and write SRAM.
My question is: I can not set the program or data memory address in
the Nios setup screen to this memory. Why not?
Also: How does Nios determine where a malloc() will allocate memory

Hello,
I want to recompile the bootloader for the Nios processor. The reason
that I want to do this is:

- I want the Nios code to be in a different sector as the FPGA
bitstream

There are several other OS'es ported to the Nios II already, such as

four-year-old promises that Altera and Red Hat were working on it.
