But now the PCI bus is reaching its performance limits. No longer able to scale in either clock frequency or bus width, PCI bus has no more bandwidth gains to make. It is time for a replacement.

PCI Express 7.0快速发展，PCI-SIG 18日宣布接近完成，最终规范今年稍晚发布。PCI Express 7为现代主板基础，现为0.9版，PCI-SIG定义为“最终草案”。一年前还停在0.5版，最初2022年撰写。 尽管PCI ...

PCIe superseded PCI and PCI-X. Unlike its PCI predecessor, which used a shared bus, PCI Express is a switched architecture of up to 32 independent, serial lanes (x1-x32) that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

But what does it take to get started with ISA or PCI expansion cards today? From top to bottom: 8-bit XT bus, 16-bit AT/ISA, 32-bit EISA. An important thing to note about ISA and the original PC ...

As the CPU speed reaches 3GHz and beyond, the I/O performance of a PC has increasingly become the bottleneck of the overall system performance. Traditionally, the I/O- subsystems are connected to the ...
