Dear friends:

I want to implement a dual core cpu with VHDL...but now i have not any
idea about it...I'd be thankful if anyone can help me about it...


Sincerely yours

Hi

how about starting from a single-core assignment.

But, since you seem to be determined:
1) will both cores access the same memory address space?
2) will they have different tasks assigned to them? Can these tasks be scheduled
independently from each other?

Dear Amir As you know design of CPU is not an easy task to peruse, What I would like to know is have you ever been involved in designing a simple CPU before? During my MSc I designed a simple 20MHz DSP processor (32bi data bus) and it took me about a year.

You could use JOP. All files for a multi-core JOP are part of the repository. We had last week the first time a 8-core version of JOP running ;-) Cheers, Martin ----- Original Message ----- From: amir.yazdanbakhsh at gmail.com> To: cores at opencores.org> Sent: Monday, January 14, 2008 10:42 AM Subject: [oc] dual core...

Well, that sounds like you should start by using a single core from a
multi-core design, i.e. the S1.

If you want to write your own core, multi-core capability is just one of
a lot of design considerations. Certainly one I wouldn't start with.

First the wheel, then the skyscraper. Help yourself with this book: http://www.amazon.com/Computer-Architecture-Quantitative-Approach- Kaufmann/dp/1558605967 Whenever you've read and fully understood it, I recommend you to take a look at the OpenRISC processor in opencores site.

Dear friends: thx a lot for ur consideration...I've implemented a single core for one of my courses and i also read that book completely and scrutinizingly. i think i have base knowledge for implement this project....but i think it needs more than one person to involve in this project...i want to implement something that is valuable.i don't want this project to be so complex like a Intel processor but i want this to have base principles. i'd be appreciated if give me any ideas that u have!!!
