Question on FIFO

[Amit]

Hello group,

Does anybody know what a single port FIFO is? I need to implement a
VHDL code for this matter but I must understand what it is first.
Either link or any online source.


Your help is appreciated
Amit

Wikipedia is a good source of short information
http://en.wikipedia.org/wiki/FIFO

But maybe I misunderstood the question...

That would be a FINO
First In, Never Out

That's a good plan.
Ask the prof.
Maybe he means a bidirectional port.

I don't have VHDL code for a FINO, but here's a datasheet:

Maybe the homework problem has to do with making a FIFO out of single-
port memory?

Hello group,

Does anybody know what a single port FIFO is?

Never heard of it. I would guess it is a FIFO with a combined read/write
port. An input such as RWN (Read/write-not) should control the direction of
the port.

A least you don't have to worry about clock domain crossings, as there can
only be one clock with a combined read/write port.
