totally different animals
pci and pcix are single ended, around 100MHz; pci express are differential, around Ghz
the architecture scheme is also different

| Can you tell me where 3.3V PCI is ued? I observed the connectors on my computer's motherboard and some PCI devices and found that only 5V cards are used in home PC's.

The main difference between PCI & PCI_Express is -
pci - parallel shared bus protocol
pci express - serial point to pint protocol

| 3.3v Is Commonly Used This Dayd Days, In Fact PCI Latest Standard 3.0 Is 3.3V Only. 5V PCI Are Old Board.

Is this difficult to implement a FPGA-based PCI card?
I'm planning to do this project but I don't know where to begin?
Can some one share some documents on PCI?
has any project over FPGA-based PCI card interface been done before?
Thank you in advance!

About PCI Express technology
PCI Express technology is the new industry-standard I/O targeted to provide local connectivity across desktop, mobile, enterprise and communications platforms. PCI Express resides at the center of enterprise interconnect innovations anticipated across storage, networking, and clustering and workstations. Next-generation servers, utilizing PCI Express technology, will offer powerful and cost-effective computing platforms, scalable hardware building blocks, market-tested best-of-breed solutions, and enterprise-class reliability, availability, serviceability and manageability.
http://developer.intel.com/technology/pciexpress/devnet/index.htm
The I/O Revolution Has Begun
PCI Express* architecture is a new chip-to-chip interconnect that offers overwhelming benefits to the communications and embedded industries over other niche technologies. The enormous benefits of a common chip-to-chip interconnect for board-level designs encompass the entire ecosystem of computing and communications silicon manufacturers, silicon Intellectual Property (IP) vendors and equipment developers.

| If you want to do a FPGA project about PCI Express, you still need a high speed interface circuits which is actually a SerDes.

Simply put NO you can't. PCI express and PCI are 2 totally different connectors sets. They are NOT interchangable.

hi to all...i am doing pci express project ...i am facing difficulty in transaction layer...how to calculate byte count and how the partitioning of the read completion data is done based on RCB.
thank you,
hope u will help me.
