LIFO ???

hi @ all

I use the System Generator.
I need a LIFO. I didn't find on in the Xilinx Blockset.
Does some one know where I can get on or how I can built on?

thanks for your time

Re: LIFO ???

There is not a LIFO available in anyy of the Xilinx blocksets.  You will need to build one from the available blocks.

This will include a memory block and control logic to keep track of the write address to know where to read out from when requested.

Re: LIFO ???

It can be implemented by a dual port RAM. The write address counts up while the read address counts down.
