I know that PXI utilizes the PCI bus alongwith the rugged eurocards defined in the compactPCI standards.
However, I was looking through some images of compactPCI systems and they look similar to the PXI standard.
My question over here may seem very noob but I was not able to find much information on the web when I search for compactPCI vs PXI.
There has to be some modifications over compactPCI which led to the PXI architecture. I also like to know how does compactPCI work, like apart from the chassis, what acted like a controller? Were compactPCI controllers(similar to PXI controllers) available? It will be great if someone can share a pic of a compactPCI system, I mean complete chassis, controller and cards? I browsed through some web links such as
which looked quite similar to a PXI system and I am not able to figure out the difference between the two.
Is it that the chassis backplane in a PXI system is a compactPCI and the other features like cooling, power, drivers and software architecture are different?
Or are the clocks, triggers, star triggers properties of PXI and not of compact PCI. I know PXI (because it is implemented on cPCI) is backwards compatible to cPCI, which means all features of cPCI should be there on PXI. I want to know what features are additional in PXI over cPCI.
Any leads or relevant links to see will be appreciated.
Thanks !
