Hi,
Has anyone done any performance comparison between a device from the 53x series and a 54x series device they would like to share? We are currently thinking about an upgrade.
I'm specially interested if the comparison is on an algorithm in userspace.
regards,
Mattias

Probably the biggest difference is the DDR memory interface; your cache line fills will be quicker. The core is pretty much the same however as the 53x family, except for a double width memory infrastructure (32 bits).
As to how much faster that will make your code... well that depends exactly on what the code is doing. If it requires a lot of access to DRAM, then it might be quicker.
