PCI and PCI-X are not directly compatible, and you’d be forgiven for thinking that means you’re out of luck if you need to use a PCI-X card in a machine that only has basic PCI slots.

This is roughly the same as a PCI-X 64-bit connection (at 133 MHz) if four lanes are used (~1,064 MB/s). Here the PCIe lanes are clocked at 2.5 GHz, with differential signaling send/receive pairs ...

PCIe superseded PCI and PCI-X. Unlike its PCI predecessor, which used a shared bus, PCI Express is a switched architecture of up to 32 independent, serial lanes (x1-x32) that transfer in parallel.

Synopsys VC Verification IP (VIP) for PCI Express (PCIe) provides a comprehensive set of protocol, methodology, verification and productivity features, enabling users to achieve rapid verification ...

In addition to the high speed and limited pin count, its backward compatibility with legacy standards such as PCI and PCI-X have been major factors in driving the market adoption. PCI Express offers a ...
