[OpenRISC] OpenRISC Digest, Vol 17, Issue 4

[jallouli kais]

https://openrisc.io/software  
For building a  software, OpenRISC is supported by a 32-bit GNUtoolchain offering C and C++ support. The toolchain is available inseveral forms, depending on your use case.   
   -  or1k-elf for bare metal use, based on thenewlib library. 
   -  or1k-linux-uclibc for Linux application use, based on theuClibc-ng library. 
   -  or1k-linux-musl also for Linux applicationuse, based on the musl library. (recommended over uClibc) 
   -  or1k-rtems for building software that runs onthe RTEMS operating system.

 Should I instal the  gnu toolchain for compilation ?

I know that mor1kx is more perfermant than or1200. But I chose or1200 since it contains a dsp block. Does mor1kx contain a dsp?I just want to test it on an example c soft to verify its working.Can you help me. I am a debutant.I want to use it later in order to integrate it in network on chip

Hi,

I've forwarded your mail to the correct mailing list, please reply to
that one.

The most recent (and recommended) implementation of or1k is mor1kx. You
can find the source code here: https://github.com/openrisc/mor1kx

How do you want to simulate? In Verilator? Or in Icarus?

If you just want to simulate a C program, you can also have a look at an
instruction set simulator, such as https://github.com/openrisc/or1ksim.

what do you mean by a "dsp block"? It's a CPU, after all. The
performance is pretty similar IIRC, 1 cycle per instruction for most
instructions.

In this case, us or1ksim.

If you are looking for a system including a NoC you could have a look at
OpTiMSoC (https://optimsoc.org).

For the NoC,we have our NoC.For testing a soft c code;  I  must installing  his toolchain ?Thanks

what do you mean by a "dsp block"? It's a CPU, after all. The

What do you mean by "his toolchain"? For information how to use or1ksim, 
see https://github.com/openrisc/tutorials/tree/master/or1ksim and many 
other resources on the Internet.

Of course. Use the or1k-elf toolchain if you're not using an operating 
system.

And please change your mailing list subscription from digest mode to all 
emails. That makes answering easier and keeps threads together.
