Emerging Chip-to-Chip Interfaces: Making Connections in Next-Generation Systems
In-Stat/MDR, Aug 2004, Pages: 31
This report identifies the key influential standard chip-to-chip interfaces, and forecasts the uptake of each. Specifically, the report looks at the penetration of HyperTransport, PCI Express and RapidIO, and also provides insight into the market/application segments where they are more likely to succeed.
PCI Express is just hitting the streets. Despite a few early missteps, few would doubt that its proliferation will be rapid and complete at least in the PC arena. Its ability to reach beyond desktops, notebooks and servers remains to be seen. HyperTransport, on the other hand, already has a track record not only in the PC market, but in game consoles and network switches and routers, as well. Even with its head start, though, we do not expect HyperTransport to be able to keep up with the sheer numbers that PCI Express will be able to amass. The market for RapidIO has taken more time to germinate but we see some embedded markets in which RapidIO will find a warm welcome. Most notably, in 3G digital cellular base stations. More broadly, though, watch for RapidIO anywhere there are embedded systems with host controllers surrounded by a stable of DSPs.
