Why Xilinx Ten Gigabit Ethernet PCS/PMA IP Core 32-bit version use less resources than 64-bit version?...

[Qiu Shui]

The 32-bit version should have better latency performance but I think it\'s more complex, so it should use more resources.

But as the link below

https://www.xilinx.com/html_docs/ip_docs/pru_files/ten-gig-eth-pcs-pma.html

32-bit version is better in all kinds of aspects of resource utilization.

If the 32-bit version has better latency, needs less resource. What\'s its cost to get these advantages?

I\'m totally confused.
