ECOS

[hjcho]

Hi,

IÂ’m Hyeonjoong Cho, a Ph.D student in Virginia Tech. We are looking for an 
appropriate hardware and software for our project. We initiated our project 
about the scheduling algorithm in multi-processor environment. As you know, it 
is about the development of an efficient algorithm to allocate tasks to multi 
processors. So, we need the operating system supporting SMP board and 
developing environment.

We found out your ECOS in the web and we have some questions to decide whether 
it is appropriate for our goal.

1.	Is ECOS supporting the SMP(symmetric multiprocessors)? If it is, what kind 
of board and CPU can it support? Can we purchase them together from you 
because we donÂ’t have any plan to develop hardwares.

2.	I want to know the price of OS and development tools.

3.	Can you tell me your opinion about whether your OS are appropriate for our 
project?



Thank you in advance.

Yes it does, and it currently supports a standard PC with SMP in the 
public eCos port.

You don't need to purchase eCos: it's available from the web site: 
http://ecos.sourceware.org/

You only need to pay money if you want things like a CD-ROM sent to you 
(link in sig) but that's a convenience thing.

The eCos kernel comes with its own schedulers, although it was originally 
designed with a plug-in scheduler architecture so you can add your own 
scheduler in addition to the ones already there. Hopefully whatever you 
add should be able to fit into the existing design.

Currently only the "multi-level queue" scheduler, which is the default 
scheduler, supports SMP.

If you do make any interesting enhancements to eCos, we'd love to hear 
from you.

Probably not, since eCos is not an embedded Linux system.  It might be
possible to run your applications under eCos, but not without 
modification.  (For example, the packages that you mention have been
ported, but this is probably only part of the issue).

I don't think so because eCos is not Linux :-). While we have some 
compatible APIs, anything that has as specific requirements as that is 
obviously pretty tied to Linux.

HTH,

Greetings,

I am new to eCos and I am planning on using it to run some selected
Linux applications on an embedded platform.  The application that I am
intending on running needs to meet these requirements:

Note that your system MUST meet these requirements:

You must have readline and openssl and thier respective development
packages. 
You must be running Linux 2.4.x 
You must have the Linux Kernel Sources package installed on your system.

Seeing these requirements, is eCos the right operating system for my
purpose?

Thanks for any help?
