For more than a decade the PCI bus has been the backbone of personal computers. Other systems, such as telephony and networking, adopted the technology for its cost and performance advantages. But now ...

Why the need for PCI Express?As processor clock speeds increase, parallel buses such as PCI become harder to implement. Signal skew and fan-out restrictions restrict the bandwidth achievable on a ...

Standard parallel-bus structures are reaching their performance limits. The only way to increase system bandwidth is to switch to a serial-bus structure. Although serial structures promise enhanced ...

A technique using distributed DMA offers upward compatibility for ISA-legacy devices in PCI-bus systems and provides a vast improvement in performance. The ISA bus, introduced in 1981, has had several ...
