Honored ContributorHi All,
I would like to know that "Cyclone V Devices" has hard/soft FIFO controller and it's operation speed. Could not find much from HandBook :( Can anyone help me with this? Thanks in advance. -Nayan
Honored ContributorAll FIFos are soft, - it uses memory and logic cells. Operating speed will be similar to that of the max operating speed of the M10ks of around 300Mhz, but it will depend highly on your design.
Honored ContributorHi Tricky,
Thanks a lot for reply. So, there are no harden FIFO controller in Cyclone V Devices ? -NayanHonored ContributorThe only hard IP in Cyclone V is PCIe
Honored Contributorone last question..
Does this is applicable for FIFO controllers in Cyclone III and Cyclone IV also? Once again thanks for the reply. :) -NayanHonored ContributorThere is no such thing has a hard FIFOs in any altera product. There are probably FIFOs as part of other Hard IPs though, but you wont be able to access them directly.
Honored ContributorHonored Contributoryes,
So, that memory controller is not being used for generating FIFOs> -NayanHonored Contributorthe memory controllers are for external DDR2 or DDR3 (plus the soft SRAM controllers). Afaik, there are non external memory FIFO IPs from altera, so you would have to create your own fifo if you wanted to do that.
