which embedded core is better?

Altera_Forum · ‎04-21-2005

Can anybody explain the difference between nios and arm, or other CPU, such as PowerPC.

which area does the nios core fit for?

thanks for any advice

Hi sclarkca,

Nios is a soft core processor, that is a processor implemented in a programmable logic device through a HDL (hardware description language) such as VHDL. Altera has also FPGA with "hard core" processor within, in particular Arm processor: it's a processor implemented in a dedicated hardware device, with programmable logic all around.

ok?

thanks for your apply.

I got it.

but i still confused about why the nios can be configured? which kind of operation can be called configuration.

If arm core is provided with the soft core, can we configure it as nios core? (we don't have barrier about the tools).

Hi sclarkca,

you can completly configure your Nios soft core processor:

- three different core in speed and logic occupation (e,s,f)

- cache memory

- peripheral such as uart and timer, in number and type

- you can include your own peripheral

and so on...

Arm processor isn't a soft core.

However to understand better the question you can download some ptf file about Nios from Altera site http://www.altera.com/ (http://www.altera.com/).

bye
