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 ...

Today’s digital systems, from the video game console to the complex switching elements in a communications network, rely on serial bus technology to do their job. Not surprisingly, a host of ...

No matter what, system architects are always going to have to contend with one – and possibly more – bottlenecks when they design the machines that store and crunch the data that makes the world go ...

While The Who sang about a bus in 1968 that transports people, digital designers use the same term for an electrical path that transports data. In modular instrument systems, buses can also transport ...

Moore’s Law might be slowing down CPU compute capacity increases in recent years, but the innovation has been coming at a steady drumbeat for the interconnects used inside servers and between nodes in ...

Currently dominating the desktop PC motherboard and graphics markets, the PCI Express protocol is poised to supplant PCI and PCI-X interface as the dominant high-bandwidth interconnect for the server, ...

Increasing numbers of motherboards carry PCI Express slots. James Morris explains why this new serial bus standard is replacing the older PCI parallel bus and how the move benefits video editors When ...

PCI Express (PCIe) has been around since 2003, and in that time it has managed to become the primary data interconnect for not only expansion cards, but also high-speed external devices. What also ...

RapidIO, PCIe, and Ethernet each offer unique benefits. We explain how each technology works, and examine its strengths and weaknesses. We also show why RapidIO is often the best choice for embedded ...
