round robin?

[Amit]

Hello group,

Does anybody know what ROUND ROBIN is? I'm looking for an online
article or page which describes it in digital design. my goal is
writing a round robin arbiter.

Any suggestion?

Regards,
Amit

Thanks for your response. Meantime I found this link on asic-world.com
however, there is no documentation or even comment to explain briefly
what singals are used and why?

Would you please tell me what these signals are for?


----------------Internal Registers-----------------
signal gnt, lgnt :std_logic_vector (1 downto 0);
signal comreq, lcomreq :std_logic;
signal beg, ledge :std_logic;
signal lgnt0, lgnt1 :std_logic;
signal lgnt2, lgnt3 :std_logic;
signal lmask0, lmask1 :std_logic;
signal lasmask :std_logic;

my suggestion is : do not jump onto the code straightaway. Go through the algorithm then probably you would understand the interface or may be you can write your own source code

Hello.

The round robin group of policies is a group of scheduling
policies. It sounds as if you are trying to write an arbiter for a
bus. Many texts would treat round robin policies in the context of
scheduling operating system tasks, but you can still read these and
mentally replace the concept of processing time with whatever it is
your arbiter grants. So, find a textbook on for example operating
systems or realtime software and check for round robin in its index.

Thanks Colin,

You are right because I was looking at digital design books but
nothing I found I looked at 5 or 6 book those which explain the
fundanmental or vhdl programming but nothing there.

Thanks for your response.
